The specification exists. It’s not free as in beer. This is really beside the point. Google implemented an RCS messaging client. Your cellular carriers implement the RCS endpoints the clients use.
What have you explained? That RCS is not stewarded by the IETF? That’s not the crux of the issue. My original claim was that RCS was more open than iMessage and that RCS is not owned or controlled by Google. Tell me where I’m wrong, and back it up with good sources. Or not. Whatever you’re feeling like.

Well others including I have explained it to you. It’s not open. And your comparison (SMTP) shows your lack of knowledge on the subject.
