Obviously in places where a road can have multiple equivalent

maintaining relations as well as just recording the reference.
Well, I believe impetus for route relations was Sustrans networks.
These tags went from the ways to relations years ago already, so call me
skeptical that there's no multiplexes in the UK (especially since
without any real effort inside 30 seconds, just randomly scrolling by
hand to the UK, I see that the A24 and RCN CS7 are multiplexed). I
honestly don't see why we should be treating tags related to route=road
any different than we're already treating route=bicycle.
There's not really any 'multiplexes' in the UK.
There are a few places where A roads appear to overlap.for a short
distance. But its really one road number disappearing, while the other
continues. So each section of road will only have one official number,
and only one of the road numbers will be signposted.
Yes, cycle routes do follow numbered roads. But that doesn't change the
number of the road, it still only has one main ref. If you asked someone
cycling along there, they would still say they are on the A24.
