If the provenance does not imply anything, then why indicate it at

You can buy a lousy Burgundy and a top notch one. You can also buy a
top notch PN from outside the Burgundy region. It comes down to ones
particular tastes rather than a name. Two PN's from the exact same
vineyard but different wineries, winemakers etc. can be totally different.

The other extreme is to place so many limitations on an appellation that
all the wines end up tasting the same, often modeled around some fuzzy
notion of what is "typical", a very dangerous concept indeed because it
tends to level everything and homogenize taste. Concepts of the
"typical" are so subjective that they are not even worth discussing.

I prefer to let a winemaker do what he knows best and let the consumer
decide what they like. Gives the consumer more variety.
