SNMP wouldn't restart a failed process nor would it generate alerts. It is simply too generic for the requirements outlined here. The proposal does not talk about modifying monit, just using it. That wouldn't trigger the AGPL. I think the idea is to have a tight monitoring loop that scales: so executing the monitoring loop in-situ makes sense.
