Of course, I see revno used on a regular basis. But I've very rarely
had to look them up. And I basically never use them myself.
My point is that someone who does need to look up what exactly were
the changes referenced on the bug tracker, might find the revision map
useful. That someone doesn't have to be called Stefan Monnier,
obviously.
