I think it is fair to consider that over time, we need to revisit how 
things was designed and make changes. It might be better to run a 
separate daemon for the monitoring protocol, and it could be providing 
the traditional monitoring protocol or something new, or both.

Monitoring as such is an important task, and some of the NTP clients 
might be servers in other contexts, and then it makes sense to monitor 
that they got their NTP time into shape. There is however many ways to 
slice that fish.
