It was initially implemented in #5871 for Godot 3.0, but never really completed or thoroughly tested for most platforms. It then stayed in limbo and nobody seems really keen to finish it, so it's better to remove it in 4.0, and re-add eventually (possibly with a different API) if there's demand and an implementation confirmed working on all platforms. Closes #8770.
