This is not available, and this is something we are unlikely to add,
because there are many services where such behaviour is not desired,
and automatic restarting is something to decide on on a case-by-case
basis. For example many of systemd's own daemons operate in a
start-on-demand + exit-on-idle way, and it would be seriously wrong to
automatically restart them whenever they exit, because they are
explicitly designed to exit all the time, and that's OK. If you'd turn
on a global switch that restarts all services when they exit, then
you'd effectively break all daemons that work that way, including half
of systemd's own.

Sorry!
