Wow. I'm amazed that was considered "novel..."
Some of the first things I was taught once I was working in industry was
to try to design connectors so that they could be plugged in backwards
and everything would still work... or if that wasn't feasible (i.e.,
you'd just about had to double the number of pins), at least verify that
*nothing will blow up* if someone does plug one in backwards if, for
some reason, you can't use mechanical polarization to avoid the problem.
(Similarly... try not to put identical connectors side-by-side on a PCB,
particularly if swapping those two connectors will blow something up.
We had this exact situation at a PPoE, but I never could convince a
production manager to change or at least move one of the connectors --
he'd go on about how we "just shouldn't hire" people who'd ever make the
mistake of plugging them in backwards. He changed his tune after one of
his own guys did plug them in backwards, killing the boards, and his
department was charged a couple thousand in repair costs...)
