This property is something I liked when we put this together
initially: i.e. have a service that can both act socket-activated and
in classic mode. But today I must say I don't think this particular
facet was a good idea, actually, because it creates raciness pitfalls:
if you start the service before its socket unit you get very different
behaviour then the other way round...
