Is it safe to gitignore the `UIElementsSchema` folder?

Question

The UIElementsSchema folder is generated when using Unity's UI Toolkit system.

Answer 1

From the forums ("official" Unity Staff answer)

This is to help some IDEs auto-complete for you when you write UXML files. Both Rider and Visual Studio should support this. But it’s 100% optional. The reason it’s “auto” generated is because it contains not just our built-in types but also your custom element types. If you find the auto-complete feature useful, keep in version control, otherwise, it’s safe to gitignore.

=> Completely optional and up to you. But it sounds like usually it makes sense to keep it. Also sounds like it will be auto-generated anyway though so it should be just as fine to ignore it.
