OMEMO adoption seems to be on a roll:

> even less servers support the features required to support it.

Does the server require something special to support OMEMO?

To answer my own question, OMEMO requires the server to support "XEP-0163: Personal Eventing Protocol". XEP-0163 seems to be more or less supported everywhere. It is sort of amusing that it was originally intended for stuff like letting your contacts know what song you are listening too. Now that it is an OMEMO requirement it has for all practical purposes become mandatory.

Well, not everywhere. But a good number with some notable services left out. Here's a chart: https://conversations.im/compliance/

You will probably need at least Message Carbons (XEP-0280)[0] to synchronise your devices and maybe Message Archives (XEP-0313)[1] to have some kind of history available to them. However this not really tied to OMEMO itself, it's just to provide what's expected of a modern IM experience. I think all servers support them nowadays, anyway.
