a) osm by itself does not have a projection. It's the maps that project
  the osm data
b) mercartor is "as precise as possible" with repect to directions. 

Sure, a map cannot be perfect and you have to select those aspects
that are important for your particular application (be it angles or distances
or just the selection of objects you show).

But that all doesn't give us a reason to add artificial, misleading and useless 
information to the osm maps.
