Ah, had completely forgotten about that.

I think that, until we know more L-numbers and get a feel for them, the
latter is more appropriate. It's easy, as you say, to automatically
convert them to a particular choice at a later date if we want.

I'll have a go at incorporating your wording about primary/secondary/
tertiary along with L roads of unknown ranking into the existing layout
of the highway pages.
