According to Lennard it's "an irritatingly common occurrence".

Mr Zinn's right on that point.

Campagnolo Ergo wires stick one's palm as they start to fray, well
before failure. It's a very noticeable warning.

Ditto with my (mostly friction) bar end shifters.  :-)

 Sticky shifting is generally when I think hum cables might need replacement
but I’m likely to ride in and though wetter conditions.

What I was describing is the first cable strands on the outside of the bend breaking and sticking out. I've been able to feel those before the rest of the cable strands, and therefore the entire cable, breaks. IIRC the shifting remains fine with those few strands broken, but it's a useful warning.
I think it's more apparent on bar end shifters than on downtube shifters, because the broken strands face the rider.
