My understanding is that this is already possible with Motec right? You can essentially "run" each cylinder as its own separate "engine" so long as you have as many 02 sensors as cylinders.

That "what has changed" is a relevant question, because scream all we want, we aren't going back to stock ECUs. I personally would prefer that as well, but the fact is the majority of the folks racing IT expressed their opinions -- and they didn't want that. Dead issue. Not sure why we are discussing it.
