Probably a good catch, but I can think of some dual carriageways which have
no classification on the ground, so it won't always be true.

If you know they are truly residential roads, then why not retag them as
such? I tend to use unclassified currently on some routes leaving urban
areas which may well be tertiary but until I know better I leave them as
unclassified. Some of these will pass through residential areas as well. But
since we don't have a hard and fast rule then that's fine for now. So is
changing to highway=road if you plan to go out and verify soon. Just don't
go mad and change areas you have no intention of visiting.
