I simply don't like the idea of duplicate redundandant tags for the sake 
of there renderer, when the only argument in favour of it so far seems 
to be less effort to calculate it. Especially when looking for a long 
term solution and considering how different this is in different 
countries with all the exceptions. Not to mention that OpenStreetMap is 
a database in the first place.
