I mean, c'mon. That was one of the biggest features of the CMI. HECK! It's fair to say that Page R is what the CMI is most renowned for, and what made it super popular back in the day. I think it's a very odd decision to omit it.
Sure, we get a sequencer of sorts in there. But it isn't even remotely as cool, flexible, and useful as the real Page R.
Including, of course (as I requested in another thread) being able to record directly into the sequencer by playing a keyboard.
