Experimental WebKit Features
Hi when delving into my iPhone settings I came across Experimental WebKit Features and noticed some of the features were switched on whilst others were not. I am not familiar with the terms or settings on this list and thus began to switch multiple settings to the odd position. Unfortunately I did not take note of which ones I had changed and only came across posts and queries on this topic after doing so. I have since read that they shouldn’t be changed from the default settings however as this has now been changed I am not sure how to reset to the defaults. Can anyone tell me please if in anyway altering the settings would affect the iPhone or performance? I am an iPhone user only and therefore do not require the ability to create or inspect webpages. Please advise thanks!
iPhone 8, iOS 15

Default Settings of Experimental Webkit Features on iOS 15.1 . Here you go.
How To : Reset Safari's Experimental Features to the Defaults to Fix or Troubleshoot Browsing Issues
Safari's advanced experimental features give you access to new browser initiatives, upcoming web tools, element changes, behavior adjustments, and other preliminary feature tests in development by Apple. If you use them on your iPhone, you can either improve your Safari experience or wreck it. Resetting the flags provides a fresh start.
Why Use Safari's Experimental Features?
Web developers and WebKit engineers benefit the most from Safari's experimental features menu since they can try out new features in development. They can then provide feedback to Apple to help the company refine and eventually implement those features in a future Safari release. However, regular iPhone users can use all the experimental features just the same.
Experimental Safari WebKit flags that are disabled by default are still being tested internally by Apple and aren't always ready for developer use. In contrast, the enabled ones are fair game for anyone. Many experimental features are useful, like preloading responsive images for faster display, lazy-loading images to reduce bandwidth, and making jump links smoother .
I'm particularly excited about "Scroll to Text Fragment," which would make Safari recognize links that highlight specific text within the webpage like Chrome currently does. Another is "Link Sanitizer," which would presumedly either remove bloat from hyperlink redirects or invalidate hyperlinks for security analysts to avoid opening up malicious content.
How Do You Reset Safari's Experimental Features?
If you like playing around in Safari's advanced experimental settings, whether you're a web developer or just a regular user trying to up your browsing game, things can get out of control fast.
For years , you could easily reset all of Safari's experimental flags back to their defaults on macOS; just go to "Develop" in Safari's menu bar, then choose "Reset All to Defaults" from the "Experimental Features" menu. On iPhone and iPad, it didn't show up until iOS 15.4 and iPadOS 15.4 . Before that, users would resort to asking for screenshots of the default flag settings so they could manually change them back one by one.
Navigate to Settings –> Safari –> Advanced –> Experimental Features, and then scroll to the bottom and tap "Reset All to Defaults." There is no confirmation prompt to deal with, so it immediately returns all the settings to the defaults.

Disabling experimental features can help minimize the risk of encountering security vulnerabilities or privacy concerns.
Regular users who prioritize stability, compatibility, security, and privacy are generally better off disabling experimental features in Safari. However, if you are a developer or have specific needs that require the use of these features, it is crucial to understand their implications and proceed with caution.
What Experimental WebKit Features Should Be Off?
When it comes to experimental WebKit features, it is generally recommended to keep them turned off unless you have a specific need for them. Here are some of the experimental WebKit features that should be turned off:

2. CSS Exclusions: This feature enables the creation of complex shapes for text wrapping and layout, but it is still in the experimental stage and may not work consistently across browsers.
3. CSS Filters: This feature allows you to apply various visual effects to elements using CSS, such as blurring or adjusting colors. However, it is still being developed and may not have consistent support across different browsers.
4. CSS Shapes: This experimental feature allows you to define the shape of an element’s content area, enabling text to flow around non-rectangular shapes. While it can be useful in certain scenarios, it is not widely supported and may cause compatibility issues.
5. WebRTC: This technology enables real-time communication between browsers, such as video calls or file sharing. While it has great potential, it is still considered experimental and may have security vulnerabilities or compatibility issues.
It’s important to note that experimental features are not fully tested and may not work as expected. They are intended for developers to explore and provide feedback, but should not be relied upon for production websites. Therefore, it is generally recommended to keep these experimental WebKit features turned off unless you have a specific need and are familiar with the potential risks and limitations they may bring.
Remember, always test and verify the compatibility and stability of any experimental feature before implementing it in a live environment.
