I don't know but that was the original reason for creating route
relations with the highway name and a second with the highway number.

Then leave what is there until someone goes and surveys it.

But your saying what I'm saying map what is on the ground.
All of the above can be included in the relation a route does not have
to be a through route. It may have side branches as in the Sutherland
example. But if the sign says Old Princes Highway then it should be
changed to that and removed from the Princes Highway relation. If it's
part of another named road then use alt_name.
Look at the Warlu Way in WA, not yet in osm, it does not have a route
number but could be included in a route relation. It's not a through
route but has a start and end and has many side branches.
Likewise the Savanah Way, some of which is in osm.
Because things change then the route relation needs to change.
If you find these things on the ground then you need to modify them
rather than just writing about it here. But don't just delete the whole
relation because one section is wrong, correct the section(s) that are
