Not to mention that if you need to pass cables through tiny holes in
walls, you do need to be able to put a plug or socket onto a wire. That
probably requires a tool (I'm yet to see a connector that could be
easily done without one).

I wonder if the way some cables are formed makes it easier to wire it
one way or another? Hand wrangling the wires into the right place to
crimp on a plug can be a right pain. You've got untangle wires, cross
some over others, and get them all to go into the plug the same
distance. It would have been a lot easier to do that if they'd come up
with a wiring arrangement different from the current specs. i.e. A pair
on 1 & 2, the next on 3 & 4, the next on 5 & 6, the last on 7 & 8,
instead of having the break apart pairs and straddle others. I
seriously doubt that would have degraded noise rejection.
