I keep finding exactly that in our 1960s built flat. It has PVC
wiring (not T&E, singles in conduit) but every light fitting I've
replaced so far I've found everything satisfactory except that the
earth wires were twisted together and stuffed up into the ceiling
space.

Yes, and common back into the 1950's too when PVC wiring started
appearing in buildings. Only seen this done on lighting circuits
though (where the earth wasn't actually required at the time).

But the early 'lighting' PVC cable was just twin - no earth. Although TW&E
did become common before earths on lighting circuits were mandatory. This
didn't stop many simply clipping off the earth wire - after all 'it' still
works without it...

I've come across this on 13 amp circuits too. Old habits die hard for some
- perhaps used to 2 pin power circuits.
