[Tagging] "width" on streets: Time for a recommendation

I think that's fine, with two remarks from my side:

You write "shoulder:width" but "sidewalk:<side>:width". It should be 
made clear that <side> (left,right,both) can be used in all cases, but 
is optional. E.g. there is no difference between sidewalk:width and 

"If the width cannot be measured exactly, but is only an estimation, 
est_width=* should be used."
I disagree here - the obvious problem is how to define "exactly" and 
"estimation". Why should the tag change depending on how precise the 
mapping is? Should we have a "est_building" tag if we can't draw a 
precise outline? How is "width" different?
