The problem here is we have 2 distinct systems, things like NH, NR, MR which
aren't part of the reference, and then the alphanumeric system MABC which is
part of the reference.
So the best I could think of in the case of MABC was to include it in both the
ref and the network, I think in the UK they only have MABC so they don't have
to consider anything else.

I have no idea if they have boundaries in place or not, so it might have caused
this to exist, then again the same could be said for most addr:* tags.

I've not done much with B & C routes, but there is a number of mismatched A
routes that chop and change names, A3 in QLD for example starts at the junction
of New England and Cunningham Highways north of Warwick, then that joins the
D'Agular Highway for a bit and then follows the Burnett Highway all the way to
Rockhampton.
The D'Agular Highway goes from S85 to NR17 to A3 and I'm not sure what happens
after it stops being the A3 it wasn't tagged.
On the other hand NR38 is only the Gwydir highway except for small sections
that it shares with the Newell and New England Highways.
I imagine some/most B&C routes may be a single segment effectively, except if
there is bridges and it might be just as easy to tag the way as it would to
create and tag a relation.
