Thing is: if there's still work on those standards, it's not apparent. Are the abandoned? Are they going to change? Especially when it comes to warnings like "Deferred after 12 months of inactivity in its previous Experimental state. Implementation of the protocol described herein is not recommended for production systems."

> Therefore, suggesting that XMPP had zero smartphone support in 2016 isn't true when talking about the actual applications.

There was (and still is) only one actual application: Conversations for Android. Support and implementation across the rest (servers and services, desktop applications, iOS) varies widely (or wildly? :) ).

> Companies actually use XMPP (despite being incomplete in the 'recommended' state) but they disable the parts which do not benefit their purpose

I know that quite a few start with XMPP (or its parts), but it looks like most abandon it when they move to mobile (for various reasons, including the ones I listed).
