Interesting, but what you're really doing (if i understand you correctly) is:

1) storing a way, plus
2) storing an approximate area (in the form of width tags applied to
nodes on the way, and then using some form of interpolation between
nodes).

The alternative is:

1) storing a way, plus
2) storing an area

...and (optionally, but preferably) relating the two with e.g.
type=area; role=center; role=area [1].
