> Clients are bad.

Yep. A friend ran an XMPP server for a while and the one person on iOS had a client that couldn't handle whatever encryption protocols the Android client supported, and the iOS client also choked on new certificates for the same domain (there was some way to accept it but the default behaviour was to just stop receiving). The killer that moved us to Signal was that someone got a new phone (something that had happened before without causing an issue) and the new phone could connect to channels but just saw nothing.
