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.
