Ah, sounds reeaaallly coooool ;-)

Any idea when this will appear on the main OSM maps?

To my knowledge, most of the mountain_pass=yes are connected to some (at 
  least highway=path) ways.

Sounds cool. Do you have an example on the map, where it already is 
rendered this way?

My observation is that almost any mountain_pass=yes node is connected to 
some kind of way, so I don't think this is very urgent.
