[Tagging] Bridge relations. Is that a 'thing'?

[Dave F]

I noticed the 4000+ type=bridge, but many of those are relations that 
try & tie the bridge going over with the way going under.

Which isn't the same objective as the first example I provided. From 
memory it was to allow routers to check for low bridges etc. AsI 
remember it, it was discredited by unsure why.

bridge:name=* can be used. It sits happily alongside name=*

Agreed
