Agreed. Back in the 2011 timeline, I printed and read the spec front-to-back to implement what was effectively an "early Microsoft Teams" (a real-time, chat-oriented client connected to SharePoint)[0] using XMPP. The spec is very easy to read, understand, and implement. I think on top of your points (and maybe adjacent or extended from that point) is that I think some entities like Google were probably seeking more wire efficiency over the XMPP protocol and possibly wanted to innovate/iterate faster. There was a wave of "real-time" collaborative apps at that time and I can appreciate the need for teams to innovate faster.
