Presumably, you would then accept, on the grounds of helpfulness you've
outlined, that writing "London" would be better than "Essex"?

No, because I probably already know it's inside the M25, but telling me
it's Essex narrows it down to a small segment of the conurbation
(roughly, between the river and the M11).
