I believe this is already what they do (at least Mapnik anyway).

Honestly, though, I'm not sure any kind of destination label belongs on
the map, except maybe at the very maximum zoom level.  As others have
said, it makes the map too crowded.

It's /very/ useful for routing, though.  I would love for my satnav to
tell me "take the exit for 10th Street" and then shut up, because it
knows I can just follow the signs.
