Hundreds of Apple engineers, other companies simply copied them. And no, they don't need me on board as I'm not a hardware engineer. On the other hand, Apple, as well as other companies, gather feedback on many fronts, including forums like this. And what I wrote previously, might be taken as feedback too.
The same applies for the weird decision of the dozen or so Apple designers ("the best in the world who agree it's the best way to move ahead") to implement an awkwardly protruding camera on iPad Pro. I can't resist the feeling that if I accidentally moved the thing over some edge at certain speed, it would rip the camera out.
