Not sure that having another tag ref:GB:nhle (500 entries) in addition to
the much better established HE_ref (9000 entries)
makes life easier for anyone. Usage of both is quite patchy, with the
former mainly around London, the latter more widespread.

I'm all for the ref:GB:* for newly introduced things, not least because it
is a more consistent format, but there will be a lot of data consumers who
use the long established tags
(Including iD for tag autocompletion)..

I'd say it would be worth having a more general discussion about this, and
identify which existing tags may benefit from migration to the newer
key format. For example, I think Russ & others have been using this for
some Western Power infrastructure such as substations instead of plain ref
(probably because many WPD substations
have 2 refs). I was certainly caught out by ref:cadw rather than cadw_ref
earlier in the year.
