IIRC their point was that SMS is insecure, so they don’t want people using SMS in Signal to think that this is Signal. With RCS, they could do what Apple will - be interoperable while providing extras with own platform (iMessage).
Admittedly, that doesn’t sound like enough reason to reimplement SMS and RCS alone would still be kind of inconvenient.
Oh that’d be nice but since no more SMS in Signal I can’t see it going back in (unless they reversed course?)
