Yes, I would like too... and I see that OMEMO seems to be the current and best protocol for xmpp. But I found only one library and the implementation in profanity. I'm not a crypto guy and I don't understand it, so if there is a simple way to add it (as optional) compile dependency, I will do. But messing up with crypto doesn't sound like a good way to go. In mcabber is the option to send commands with a fifo, so it would be possible to send (GPG and OTR) encrypted messages. With profanity, it might be possible by writing a plugin.
