Jep-0022 is a historical jep. I didn't know it has privacy issues in current
implementations, but it could be improved or dropped. If you're interested in
jep-0022 and replacements, let's start another thread for it. It's (almost)
and end-to-end issue.
Anyway jep-0022 is being replaced by jeps-0085 (chatstates, composing),
jep-0079 (advanced message processing, offline storage) and jep-0184 (message
reciepts, delivery). I admit they are much more complicated, but at least
this affects only the servers.

Hmm, these privacy issues can be server errors ... if they're server errors,
please move this disussion to the mailing lists or forums of particular
If they're errors in jeps, please report it in a new thread and mark the
places you think are bad or ambiguous.
