So, my understanding is that while XMPP has historically sucked on mobile, it's gotten better? Does anyone know about the current experience? I don't know if it's due to new XEPs or if it's just better client implementation...

I've been using it for years, so has my family and recently a group of some 60 friends with whom we communicated about a large party ont of my friend and me organised. I made an invitation site with an instance of converse.js at the bottom of the page, pointed at an anonymous group on my (Prosody) server. We just mostly Conversations or one of its forks on Android - no fruit phones among us - and Converse.js on web, higher on the same server which hosts all our other services (mail, "cloud", media, etc.). Once installed and configured it is maintenance-free, lightweight and reliable.

That is how you gain traction: by having people use it, realise the user experience is comparable or in some cases superior to that of other messaging systems - the party chat thing I mentioned above being a good example - and then realise they dont need to hand over their data to an ad broker (Google, Metafacebook, the fruit factory) or the government (all of them through some "chat control" type law).

If you're talking about the push notifications experience, then XEP-0357 solves this, but app developers have to host the infrastructure which the XMPP server calls back to and dispatches the notifications to Apple or Google. Last time I used Monal on iOS this was solved and worked well. On Android I think most apps still prefer to keep their own background connection open.

Many Android apps give the option of using either FCM (Firebase Cloud Messaging, Google's push service), UnifiedPush or polling.

Of note, Conversations and some other XMPP clients can act as UnifiedPush Distributors (i.e. they use their own reliable persistent connection to proxy notifications for other apps). Some mastodon (tusky, fedilab, …), matrix (fluffy chat, element x, …) clients use it¹
