I find it hard to imagine to use the current bw only and grainy cameras of e.g. the quest 2 for such tasks, it really doesnt feel natural. But might be easy to improve this in future generation hardware
I'm sure they chose the ones used for better CV tracking & properties, especially in low light etc, but could be easy to add a pair of true-color ones, especially for passthrough. Just checked again and the main issue IMO currently is the low framerate / blur when using it. The movement of the hands e.g. is quite uncomfortable this way.
