Most of the stuff people think are RCS aren’t though. They’re proprietary extensions to RCS that only work on Google’s text message apps, transmitted through Google’s servers, with RCS junk as fallback for other services.
It’s not actually meaningfully different than Apple doing iMessage with fallback to RCS now.
Intercommunication is still going to be bad because the standard that carriers support isn’t where all the features are.
