As an executive summary, this is the *problem*, not a mitigation.
Domain creation *should not require privilege*.  You should be able to
do it in a user namespace in which you have appropriate capabilities
without needing systemd's (or whatever other daemon's) help from
outside.

Once you fix that (which may not have broken whatever you tested with
but will absolutely break anyone who tries to use this in LXC, Docker,
Sandstorm, etc. without awful hacks) then you will have all of the
problems that you've currently mitigated.
