So... in practical terms, what's the simplest way for me to get an account on an XMPP server that supports all these modern XEPs? I could maintain my own XMPP server, but I'd really rather not. Life is short, etc. Is there a reasonably-trustworthy company that I can just pay to use their XMPP server? I gather FastMail used to support this, but no longer does.
