Yeah, that'd be what it is now, just done in systemd profile, not most
of the separate systemd profiles.

So how about we try to just always enable this instead in dbus and
bluez? Anyone got any objections, provided the below can be handled?

I peeked at bluez, and there USE=user-session exists to apply a patch
to unbreak things when user-session is disabled. Unfortunately it seems
to be needed there for non-systemd systems as well. I think we should
be able to figure things out to work in all situations there, or make
it be applied for USE=-systemd only (that's already the case there,
just it is not applied for USE="systemd -user-session" right now).
