A good 3rd of my wine collection is French.
I am pretty sure the practice is mostly non-existent in Europe. At least in appellation wines.
But when people complain that low-cost wines are better in the new world, my experience is that they are invariably referring to the fact that they can get a consistent fruit forward 'shiraz' for $13 but when they taste a cheap French wine it's nothing like that.
Fair point however.
I have found in the last couple of years some makers have started to move to more of a French style. In the world of whites, the cougar juice is giving way to a better old world style wine.
I agree there are some suspect fruit bombs out there that people think wine should taste like. I hope that is changing.
E.g., kinda like the German beer-making standard vs. "anything goes" Belgian-style ales.

I'd also be interested to know what is and isn't allowed in wine.
Old world and especially French wines are generally more neutral and restrained wines, made to be consumed with food.
Also a very high percentage of low and mid-tier wines made in the 'international' style are more like a composed semi-synthetic product made to conform to a rather homogenous consumer preference, and altered with flavourings/additives[1], esthers, enzymes, etc. than the classic definition of an 'authentic' wine (even if that itself is kind of bullshit).
