After many discussions over the years about the referencing of 'C'

I assume you mean the reference is not rendered rather than the road.
Yes. Note the frequent use of the word 'reference'.
It seems to me that, in the UK, class C roads should be exactly the
set of roads with highway=tertiary, so there is no need for a new tag.
By design or error (of either the highway authority or OSM mappers) that
is, unfortunately, not the case. I've provided Overpass queries for
contributors to check & verify these anomalies.
Even if that is not true, the correct solution would be to test the
reference in the renderer and suppress it if within the UK.
Collecting them into a unifying tag makes it easier for them to decide
how they want to do it.
