Technically speaking, those are implemented, just not stabilized, if you’re using them in the nightly, they’re just disabled in stable.

So I would anticipate they will eventually stabilize like many other features have and become part of stable.

Just want to clarify that an implementation being present in nightly doesn't ensure a timeline for stabilization or even that it will happen, as unexpected bugs in the implementation or design of the original RFC might crop up once it's actually used that makes us take the decision to push the stabilization back. This has happened multiple times (from a single version delay to things that are perma-unstable). That being said, the majority of the unstable features you're waiting for "only" need baking time.

GAT and specialization still needs a lot of magic, mostly chalk/polonius integration, doesn't it?
