What's wrong with duplicated data, though? I don't really see anything  
that will cause real-world problems, other than a marginal storage  
overhead.

At the moment we're regarding "the same street" as something of  
paramount value in itself. But street name is only one identifier, of  
use to a certain set of people in certain use cases.

For some uses, National Cycle Network route number might be the "sense  
unit": I don't think I looked at a street name once when I cycled NCN8  
across Wales last year. For others, like most modern-day driving, the  
road number might be.

That's not to say that there's anything intrinsically _bad_ about  
street names. But I don't see why our data model should favour one key  
over another.

(But I'm happy to be corrected!)
