Because overloading objects to mean many different things is a
concept that confuses users and therefore sucks arse.

Not really. You're considering users that are already very
familiar with Nagios. I'm considering the ones that have no
clue what so ever.

I doubt it. Hacking in code in Nacoma to handle nested compounds
took all of 35 minutes.

With the added problem that the service set name is horribly
denormalized and has to be printed on everything that gets attached
to it as well as everything that uses it, when it really should only
ever be printed at the sites that use it so objects can be safely
removed without leaving leftovers all over the place.

I'll have to look at a sample of that someday I think. It sounds
terribly confusing, whereas service sets as nested compounds sounds
very, very simple to understand. Noone I've explained them to have
asked about the value of them or how they work, at least.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
