Okay so how does modern XMPP protect this? When I last used XMPP, some (not all) clients supported OTR-IM, a protocol for end to end encryption. And there wasn't a function for server stored chat history (either encrypted or plaintext).
Have these issues been fixed?
It's not perfect yet, but it's much, much better than the old days.
OMEMO is supported by every major client, and they interoperate successfully. Unfortunately, most clients are stuck with an older version of the OMEMO spec. It's not ideal, but it doesn't cause any practical issue, unless you use Kaidan or UWPX, which only support the latest version.
All popular clients and servers support retrieving chat history now too.
In practice, I've been using it for several months to chat with friends and family, and haven't had any issues.
