This is actually a common case: for getty style login process the main
process of the getty service will migrate to the new scope. A service
is thus always a cgroup *and* a main pid for us, in case the main pid
is outside of the cgroup. And conversely, a process can be associated
to multiple units this way. It can be main pid of one service and be
in a cgroup of a scope.
