Yes.  If there is an uncontroversial route number that applies to a sequence
of roads, lets map it.  Yes, a relation is the best way.

The issue I have is with using a route relation with a road name to link
split parts of a named road, and including roads that don't have a name or
alternate name in common with the route, and can't clearly be identified as
part of that route by survey.

My example of the Princes Highway route from Sydney to Adelaide currently is
one such route, where choosing what roads to include is often arbitary, and
even if completed it may still not be a through route that can be followed,
and may be confused with the actual road with the same name.

I have no problem with the A10, A1, MR1, M1 etc being used on route
relations.  I wouldn't even have a problem with multiple Princes Highway
routes over sections where such a route is clear and verifiable.

Ian.
