No issue running with gnome-boxes. May miss some features, but generally there is no requirement to have systemd with cgroups-hybrid, to run it. If it's required, please explain why. !sys-apps/systemd[-cgroup-hybrid(+)]
We need it for older libvirt-5.6.0 and below (that will not start with a cgroupv2 only layout). It seems that libvirt-5.8.0 has been fully ported to virCgroupV2 (with a gigantic patchset hitting the repo in August).

Unfortunately, libvirt-lxc at least for libvirt 5.6.0 did not work properly with v2 only support. This was handled in more general terms in https://bugs.gentoo.org/691310
For reference, I am referring to this upstream bug regarding libvirt-lxc [1]. I will disable the hard dependency on the hybrid layout once we have a upstream patch available that can be applied. [1] https://bugzilla.redhat.com/show_bug.cgi?id=1770763

Unfortunately, we still need the hybrid layout as a mitigation for a bug in the libvirt-lxc driver. So restrict the dependency on sys-apps/systemd[cgroup-hybrid] to the case of USE=lxc only. This should accomodate everyone who does not need libvirt-lxc support and wants to have a v2 only hierarchy.
