Maintained?
How does one maintain K+T? Other that allowing no changes to the HVAC system, so no metal is installed within 2".
But I agree in general, I'm speaking more of statistics than personal memory, though, and the fact that the codes have always been written in large part by insurance companies. They want us to be safe too, whether for altruistic reasons or not...
Most common problems I see is improper extensions added to K&T and encapsulating K&T in thermal insulation, it was intended to run in free air with only contact to the insulating knobs or tubes, and quite often I also see more than 15 amp overcurrent protection on 14 AWG conductors, if the device is an edison fuse it will be 30 amps 99% of the time.
