You can have different standards for different use cases. So you mean that iMessage and rcs are so different that Android can't use iMessage or apple couldn't use rcs? We don't need to find one standard to rule them all. But we need to stop anti-competition behavior like allowing these protocols to be exclusive.

Used as a common denominator for basic communication, yes. Use for the kinds of rich interactions and modalities (like the "server" metaphor) that Apple, Google, and everyone else wants to add to chat, no. And that's where we get lost in "extension hell."
