That's 100% fair. Good thing it's not too difficult to assign VFIO w/i QEMU for virtual machines despite the manufacturer shenanigans. :)

The Arch wiki has a great guide here - https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVM...

It does get a little tricky if your GPUs are identical, but I've done this for years and maintain a guide for doing this (as well as the ACS-override patched kernel RPMs) for Fedora.

As far as concerns around stability with ACS override, I tend to only enable the override for the specific GPU (or other hardware) that I'm passing through and haven't encountered any stability problems or memory leaks that'd interrupt desktop or light server usage. I also used to run this for a bunch of white-box GPU hardware for a customer at a former job and it worked well for exploratory AI/ML workloads before investing in the big Nvidia DGX boxes. YMMV, of course!
