What's the useful advantage to a flush back? I don't really see any. As long as I can hold the phone, and it can lie on a table or stand without wobbling, it seems to do what it needs to.
It's not like you're stacking phones on top of each other the way you do books or magazines. (And heck if you work in repair or provisioning and actually do stack phones, it's easy enough to turn every other one 180°.)
Also I don't know where you're getting "fraction of a millimeter" from. Camera bumps are significantly more than a whole millimeter. And their function is depth, not volume -- you can't redistribute it across the whole case or anything. You'd have to make the entire phone thicker, and then heavier as well if you're putting anything into the new extra space.
I just think it's nicer honestly. There's no rational thought behind it, it just feels cleaner. I don't really mind extra weight or thickness, it's not like I'm struggling to pick up my phone. I actually have exceptionally large hands so if anything a bigger phone might be better, though I'm not terribly concerned about it.
