That was the start of the discussion in 2007, but was changed due to the 
changes (around the same time) of highway=tunnel / highway=bridge to 
tunnel=yes / bridge=yes - so using the same logic for passes seemed like 
a good idea then ...

Anyway, every solution has it's pros and cons here.

AFAIK, only osmarender at (too?) high zoom levels (from z15) and JOSM 
renders it.

I would be glad, if Mapnik would render this as well. The same 
zoomlevels and logic as for peaks (icon, name, ele at different 
zoomlevels) would make sense for me ...
