I have seen this only rarely with typical studio wiring. I have seen it
on high voltage wiring in transmitters. Although it does not damage the
ability of the wire to carry high voltage, it does make it brittle and
easy to damage. It, in my experience, usually makes a big mess.

I have seen this on a few Sony power cords, though.
