I think security by obscurity works reasonably well for ad hoc meetings,
although probing is cheap (e.g. dictionary attack). You could add
something to the server that allows to see if someone is trying out many
different rooms for activity sequentially. That would raise that cost
and help prevent abuse.
Other use cases are different from ad hoc conferences like you mention,
I guess more like a classic IRC channel that is persistent and
publically known. This would be akin to a publicly announced conference
room where potentially many people participate over a longer period. In
that case confidentiality is not the issue, but it would be embarassing
if thousands of people are dropped off because of one person trolling.
Also, it would be great if someone could somehow be granted a channel
operator role (perhaps not on sip2sip.info service, but in case of a
self installed system).

Understood. We definitely need more manpower to work on these important
projects. We can't expect you and your team to solve everything for us.
