I wouldn't say never but surprisingly rare things mains shorts in
fixed (non-portable) equipment.

Going open circuit or overheating seem to be the real problems for such
things and with thermal protection over heating is more of a nuisance
than a problem.

Fuses becoming "tired" and just becoming open is probably far more common.

Slow-blow glass cartridge fuses seem to lose their end caps with
monotounous regularity. But all the faults I've seen have related to dry
joints or inadequate cooling.

They do indeed, but I was thinking of fuses which just become open in
place. It happens a lot with BS1362 type fuse links.
