This would be a reason to avoid using (eg) a 4p4c plug in a 6p6c jack.
But I don't see it as a reason to avoid using, eg, a 4p4c plug in a
6p4c or 6p2c jack. Is there something else I'm missing?
As long as one is actually using 6pNc appropriately, no. If you're
talking about plugging, say, a 4p4c plug into a 6p6c jack (which
was one of the original situations mentioned, in particular when you
have to come up with an MMJ cable in a pinch without the actual plug),
then you risk damaging pins. Plugging a 4p4c into a 6p4c jack should
be just fine.
