There are several Windows features that rely on HyperV under the hood. Home supports them. It does not give the user the ability to run their own virtual machines though.

I don't see any mention that it'll be on Home, "General Availability" just means that it's no longer part of the insider preview

been using it in home for months it works well.

Regarding hyper-v they are only making necessary component needed for wsl2 available.
