I guess you could do that.

I'm happy enough to not have config loaded automatically, though -- it 
just seems neater to have a whole bunch of changes queued up and to have 
them all applied at once. I've never found manual reloads to be a big 
problem.

On the other hand, I can't think of any big problems with having new 
config applied automatically. It's not as if systemd will automatically 
start any new units or stop any that disappear under it, at least at the 
time of the reload itself. The one concern though is that it can affect 
future jobs, as new dependencies between units may have been automatically 
added. But maybe that's what the sysadmin expected.
