The worst part of lightning is how flimsy it feels once it's been worn in.
Plus having the connectors inside with something to line it up seems like a battle hardened design choice now. Unless you're an idiot, you're not gonna break anything.
it would be sad if they didn't try to improve on previous designs
In later revisions (at least starting with micro USB, perhaps mini as well), the cable was explicitly designed to be the part prone to breakage, as it's easier to replace.
Too bad Apple didn't wanted to give this one to the USB consortium and we'll now be stuck with USB-C (and don't get me wrong : as much as i love the lightning connector, I vastly prefer a standard connector for everything, so USB-C it'll be).
Also, more ports on USB-C make for better "alternate mode" functionality, where some data lanes are re-purposed (with an analog mux) for another use, like displayport, or audio DAC.
USB-C is a very capable plug system, so I'll be happy if everything converges on this one instead.
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.
