[Tagging] Cycle route relations, networks and refs

I've encountered two fairly widespread issues with bike route tagging
and would appreciate help sorting them out.
In parts of Germany and elsewhere, networks of local/regional cycle
routes are grouped into regions. The Nordrhein-Westfalen network is a
The master relation
is tagged with type=network, which is perhaps appropriate (insert usual
'Relations are not categories' citation here).
However, its child relations are tagged with type=route:
which is not appropriate. As the osm.org geometry shows, this isn't a
route, it's a collection or network of routes.
A second issue is the misuse of the ref= tag in these relations. The
ref= tag is intended for a number that appears on a sign or other
on-the-ground evidence. It is not "some arbitrary bunch of letters I
made up to get it to render". However, it's being used as the latter in
this (ref=NRW) and many similar cases.
The most "correct" way forward would seem to be:
- break the child relations up into individual routes
- group these together within a parent type=network relation
- remove the ref tags
The first step would, of course, be Hard Work.
Thoughts and suggestions welcome.
