I'd like to suggest that most people don't use the comments feature for
long term or extensive storage of notes about hosts and services. Are
you sure you're using the right feature of Nagios to accomplish your
goal?

This is really what the notes_url feature is for; have you looked at
that? No worries about upgrades there and you have the flexibility to
store the information any way you like.

If you want to optimize the comments code, without using a database 
(nagios has moved away from that for a number of reasons), I'd suggest
subscribing to nagios-devel. Ethan doesn't monitor this list that I am
aware of and he's the only one that has any say in what gets added.
