The property is never set by systemd, only reset after a stop or restart or reload. It may externally be set to mark the unit for a later restart/reload. I wasn't sure whether to configure the property only for the types where this makes sense (Service, Swap, etc). But Restart() method is defined on the unit, and also having this always under the same property name is more convenient.
