Yes im also concerned about this. Putting stuff into PEP and using +notify
But it clearly does not scale well at all.
You might be ok for 20-30 contacts but not for 300
Just from the top of my head
I'm sure there are even more.
This will soon reach an amount where a client simply can't implement these
XEPs because of performance reasons.
At some point we should make this scaleable.
