People really don't seem to understand that in the electronics world, one single millimeter can make worlds of difference.
You absolutely can cram so much more stuff in "dumber" electronics, but phones are even more constricted in design, because they need to send and receive signals of different types, so feedback and signal noise are concerns.
Adding in even slightly more space allows for much better design, because you have more tolerances to reduce signal noise. It allows dozens of wires for camera sensors to route better. A 20% longer battery life. Heck, just being slightly more ergonomic and less droppable is a bonus to slightly thicker phones.
I didn't even consider signal noise until I got into fpv drones and rc stuff, it can mame a ton of difference if you have a single wire 2mm out of place. (and crash your drone because the motor interfered with your antenna)
Thiner≠better.
Wildly appropriate username here. Also, 100% correct.
