Exactly. Except for cases where I _know_ the connector was designed to be
able to withstand being plugged in backwards (e.g. IDE), I would _never_ try
reversing a cable 'on spec'. The chances are just too big one will kill
something.

(Amusing factoid: QBUS cards have the same thing, they are designed so that
you can plug them in backwards, and not kill things. I am somewhat ashamed to
admit that one one occasion, I actually did this! Luckily the engineer who
did the QBUS saved my behind.)

And how many times have you melted something down, doing that? :-)
