Actually Richard, on consideration, I agree with Gorm's proposals.

As you see from his example top-right it *does* break the secondary highway.

"People are not saying "my routing can't work because fords are in the 
highway namespace"."

Then that's bad assumptive programming by the routers & not a valid 
reason not to change it. As is disrupting Garmin & osm2pgsql.

In fact tagging it highway=*, ford=yes makes it *easier* for routers as 
they have to do less checking to see whether the ways on each side are 
the same.

To change the nodes is not essential but makes it easier for all to have 
consistency.

As others have mentioned the renderers need to be informed but I don't 
see that it's too difficult to change.

Cheers
