For me, not too fussed about that (haven't used that code I think). In my case, there is some encryption stuff missing which needs fixing (and, no real solution around it). And I wish it was fixed :(
I have a wine patch developed using an LLM that adds the missing stubs, but, I can't submit that to wine (and whilst the code works for me, it might not work for other people anyway). So, I'm really stuck with virt-manager for now unfortunately.
