I'm sure mechanical engineers calculated the entry, insertion distance and wiggle room, so that you can't apply any relevant force onto the notch inside.

Wish they had done the same with Micro-USB, those get real flaky after a while.

They always do. These things have mechanical physical standards as well as the electronic/software side.

Micro-USB requires more force because of its 2 teeth underneath, that's made to latch onto the socket. That was a mistake. In comparison, Mini-USB don't have this problem and slides straight similarly to USB-C in that sense.

A lot of thought process goes into this mechanical interaction of male/female plug/sockets.

I design/3d printed a lot of mechanical stuff for hobby for some years now. You can't make stuff work without calculating these tolerances. I am sure professionals who work on standards know/do better than me.
