I have never seen any of this in real life.

However, all of this is in the RCS spec. If Apple implements the RCS spec beyond the bare basics, all of this should Just Work.

RCS is much more than just "SMS but via weird HTTP" and things like chatbots and interactive components were one of the selling points towards ISPs to bother supporting it.

Unfortunately, nobody seems to bother dealing with the standard. Now Google is at it again, selling "RCS for business" when the RCS standard itself is supposed to be used in a federated, carrier-to-carrier fashion just like SMS.
