Hi Alex, That was what I originally going to implement.
However we will need to keep a list of individual routes for QLD NT and WA since there is no way to separate national and state routes in those states to give white or blue shield respectively. The engineers pushed back against this as we much prefer leveraging OSMs rich data model to do this sort of thing automatically. To understand the reason, say a state one day changes the designation. If we hard code the list of routes some one has to remember to go and update the list. If we just rely on OSM tags then this will be picked up automatically when a local user updates the ways.
