> deal with the case of an offline client and still offer forward secrecy.

Wasn't that addressed by OMEMO, the OTR "replacement" protocol?

Yeah. Basically Signal protocol over XMPP. It uses the XMPP server for the stored/delayed cryptographic state which is why you need a server that can do PEP (Personal Eventing Protocol) if you want to do OMEMO.

OMEMO has pretty much replaced OTR in the clients so if you want simple/stateless you are left with one of the two PGP flavours.
