How long is PhysicalAnimationComponent Experimental?

Hello.
In UnrealEngine 5.3, PhysicalAnimationComponent remains Experimental as before.
This feature has existed for quite some time.
In 5.2, it seems that PhysicsControlComponent was added as an Experimental feature as well.

Is PhysicsControlComponent being developed to replace PhysicalAnimationComponent?
Why has PhysicalAnimationComponent remained Experimental for so long?
