Right, but that R1 chip is going to be doing work constantly, and can't be moved without increasing the latency (decreasing quality and increasing issues with vertigo); so you have to work on thermal regulation within the headset anyway. So comparing the whole package of "R1 in the headset, M2 somewhere else" vs "R1 and M2 both in the headset", is the slight reduction in heat to be diffused from having the M2 elsewhere worth all the hassle of having to figure out where to put it? It sounds like Apple's engineers have gone with "no". Time will tell.
