QubesOS is very cool but I've always thought it'd cool/better if it was a patchset or repo on top of an existing distro like Archlinux or NixOS. I think that would be useful so you could adopt features from QubesOS individually and swap out different components. For example, it'd be nice to use KVM (QEMU or even crosvm) instead of Xen or build a Wayland based system instead of X11.
