Can we do (b) now and differ adding any HW resources to cgroup until
they are clearly called out.
Architecture and APIs are already in place to support this.

Sounds fine to me. The only thing I want to avoid is pie in the
sky "future proofing" that leads to horrible architectures. And I assume
that's what Matan proposed.

NO, that not what I proposed. User-kernel API/ABI should be designed with drivers differences in mind. The internal design or internals APIs could ignore such things as they can be changed later.
