I got the impression the primary motivation to do this is so the BCM2712 (and future processors) can move to smaller process nodes (less power, more speed) but keep things like 5V tolerant IO, ADCs, analog features which work better on 40nm. Going forward they will be able to keep a consistent set of IO whilst iterating to new BCM variants without hitting constraints as a result of smaller process nodes.
