[Tagging] Superroutes - good, bad or ugly?

If a "/superroute/" has an official status (/like this one: https://www.openstreetmap.org/relation/20773/), I'm all-in for that.

If instead it is something "/invented/" by the mapper, than I'm all-against it.

Can you please provide more information/examples/context?
