A nice property of systemd is that it takes care of setting up
the environment for each service.
PAMName can be considered one of the pieces of the environment.
It is expected that services will eventually start taking advantage of
it and cease to implement these things themselves. It makes them
simpler.
See http://0pointer.de/public/systemd-man/daemon.html for how
"new-style" daemons are made simpler.

As systemd takes away the responsibility of creating sockets
from the services when it offers socket activation, it makes sense to
offer the option to filter the activation requests using libwrap.
