Utterly bizarre they're milking a number so much to provide some sort of route identity.

imo it should be banned. A route number should go from A - B.

Not A - B, or A - C or A - D or A - E.

Similar discussion for variants which should be variants, so no letters unless it's A to B via C or A - B via D, again not A - B, A - C, A - D

It's just confusing for the sake of it.
