What systemd currently does is: 

    If the reload fails it shutdowns the service and informs you about
    the failure.

What systemd probably should do (and what is now in the TODO list) is:

    If the reload fails it should leave the service as is but informs
    you about the failure.

That should make it easy to plug in check scripts via the ExecReload
directive and make the need of an additional directive unnecessary.
