Thanks Paul,
"addr:village" makes much more sense to me.
As for post town tagging, maybe it needs a run across the mailing list or even a poll on the forum.  The last round brought forth gems like https://lists.openstreetmap.org/pipermail/talk-gb/2019-January/022424.html and https://lists.openstreetmap.org/pipermail/talk-gb/2019-January/022413.html (and, to be fair plenty of others with different views).
Cheers,
Andy
