App for XMPP with OMEMO support?
While Kaidan would seem to be a logical choice, it doesn't seem like OMEMO support will be available soon (see https://invent.kde.org/network/kaidan/-/issues/254).
Dino is GTK based but seems to be working ok if the feature/handy
branch is used (see https://github.com/dino/dino/issues/178). Would it be possible/make sense to package this (apparently postmarketOS does so)?
