We need to be careful about removing tags because it could cause 
renderers to fail (or at least not work as expected). For example, I 
think the is_in tag is added after the place name in mkgmap when 
creating the "city" POIs.

Maybe the solution is to have a list of depreciated tags and maybe give 
people a year or two to stop using them before they get removed.
