I think we're confusing two things here. ssh via socket activation is of course a brain damage done solely by Ubuntu. But systemd goes a long way to make sure it hurts, because `ps ax | grep sshd` will definitely show you that /usr/bin/sshd is running. Except it's not it. But maybe that's Ubuntu thing as well, not sure here.
