The polkit access control driver is the only one we support, and it is not
something that end users can replace as this is not a public plugin system.
Any alternate impl would have to be part of libvirt core.

I'm not sure what docs you are referring to, but the polkit driver is in
perfectly good condition. It is not restricted to just checking PIDs,
in fact PID is largely irrelevant - user name and group membership are
the important things to check. Ther is an example in the source tree at
examples/polkit/libvirt-acl.rules showing a simple RBAC approach to using
polkit.
