Hmm ... it sounds as though one might define a "deep" fishbelly as being consistent with both definitions, and a "shallow" fishbelly as consistent with only the less restrictive one. Can that be expressed quantitatively?

Please keep in mind that it is not the purpose of a dictionary to coin new terms, but rather explain terms that have come into common usage. As such, they lag behind the language.

It would appear that the term was first applied to passenger cars with deep sills AFTER cars with straight sills began to be built, since before that there was no reason to differentiate, as all passenger cars had deep sills. The term then evolved to mean ANY application with sills of unequal cross section over the length of the car.
