'Sleep/Wake' for an AMD laptop, and related questions

[Boryeu Mao]

I started using Qubes (r 4.0.4) and am on 4.1.  Everything works well except 'sleep/wake', which my laptop (Dell, ryzen 3450u) is capable of (on Debian 11).  Two related general questions:

(1) Is it correct to think that there is no easy fixes, as suggested in some on-line discussions, and it best be resolved with potential up-stream changes?

(2) There were discussions of the possibility of Debian as dom0 OS, though at a lower priority at the time.  There was also a Debian devel page on this topic that hasn't been updated since ca. 2018.  Is this still being pursued?

Thanks in advance for any information.
