That documentation is near useless, and doesn't describe at all what the classes are supposed to do (other than inheriting from TCustomAttribute)

You might better look at the Compiler Attributes documentation:

With that said: even if we add those attributes to the RTL this does not mean that the compiler suddenly handles them as that page describes.

Including the definitions will allow people to compile their code.
The compiler simply does not honor the special meaning of these attributes - that's another feature request...
