Of course it couldn't. Messaging was moving very rapidly with new features like stickers, reactions, expiring messages, phone number IDs, SMS fallback, stories, bots...and all of this had to be presented a very integrated and user-friendly package. You simply can't move that fast (or move much at all) with a huge standard like XMPP with 20 different clients that barely change.

Not to mention that in this capitalist society, messaging services are incentivized to grow at all cost because user-base is the best fuel for monetization. Holding onto XMPP federation like Google did in XMPP's final years of relevancy would be suicide; you would be helping your competitors while gaining nothing.

But by that same token, could it be possible for a new standard which incorporates all those features to become viable when the messaging space has stabalised?
