Well, some alterna people consider a locality line to be 'generic' after the F2 generation or so, so your thinking has been taken up by some folks. These are folks, keep in mind, to whom 'locality' means a particular couple miles of road cut. They are serious about locality.
Note well what I said about taxonomy, too: the locale still has future relevance to the taxonomic identification of future offspring, which is entirely lost when mixing at any level.
Another issue is (a big deal in dart frogs; in snakes soon, I'm certain) that certain localities have been extirpated in the wild; what we have in captivity is all there is, and if people don't pay attention to locality, that genetic distinction is lost from the world.
