Having to field endless complaints about people being in the "wrong"
county can't help either.

That's a self-inflicted injury because of the way they encourage other
(non-Post Office) people to use the database as a way of defining the
hinterland of where people live. As a result, it has a huge number of
false positives and negatives, and simply deleting some of the database
it not necessarily going to help very much.
