Agree completely.

I would add: I expect many situations where data will be destroyed
afterwards: If ways are split for whatever reason, this would result in
two ways with identical start and end values describing another
situation. (e.g if you have start=2m end=3m you will get the same
section as 2m-3m/2m-3m). You couldn't split a way without measuring the
width at the splitting point - as a mapper you would have to delete the
width:start/end tags if you split a way without knowing the width on
this point, but no one would dare or be aware of it.

=> "... I expect many [or at the moment: all] editors that would destroy
the data."
