Fair enough, but if the rendering/router/whatever won't differentiate 
based on those tags, it won't help any the map user. Thus your point is 
moot if e.g. the rendering is based solely on surface=* (or actually, any 
particular subset of those "helpful" tags).

But this footway/path/trail controversy is about not rendering object that 
are physically very much different the same.
