[XEP-0384: OMEMO Encryption](http://xmpp.org/extensions/xep-0384.html) seems to be a good (possibly even better) and simple alternative to [XEP-0374: OpenPGP for XMPP Instant Messaging](http://xmpp.org/extensions/xep-0374.html). Thus my request to look into that as a replacement (and thus supersede e.g. kontalk/androidclient#633).
