Most residential POTS service in the UK is fully digital from

Yes, it is.

No it isn't. The line into my house (and everyone else's house) is
copper, delivering an analogue voltage to an analogue handset.

OK, if you want to be picky, it's digital up to the point where it
leaves the last distribution box.

That's not being picky. It's a vital factor. The service available
to a user is limited to what will go down an analogue connection. No
matter if that connection is only a few inches long, it's still a
bottleneck.

Utter bull****. The signal has to be analogue when it enters the house
- that's not a bottleneck, that's delivery of a *useable* POTS signal,
just like the output of a DAC in a hi-fi system. If you want something
else coming into your house, then it's not a 'phone line, and can't be
described as providing a POTS.
