I'm don't understand what advantage is to be gained by recording who
runs what roads as the main means of recording them.It isn't obvious on
the ground, which is where we're getting our information from, and it
isn't obvious to an end user, who we're trying to communicate with.

I'm pretty sure that's what most of us are doing, or rather we are using
the signs as ground-based evidence of what kind of road they are.
This seems sensible to me because to do navigation of some kind you want
to see on the map a representation of what you see on the ground. Unless
you're a local authority or the Department for Transport, you just want
to know that if you see green on the map you should be looking for green
signs in the UK, reversing what the surveyor did.
