100% strains are getting lost. The true skunk #1, that you could smell 300 feet away, that is gone. Plenty of skunk #1 strains out there, definitely smelly weed out there, but man, if you were smoking in the 90's and had true skunk, you'd know.
Things evolve rapidly here (US) and with legal markets, consumer demand is really driving what producers are growing and the always evolving game of mix the hot strains together. In the 80's & 90's people would breed with afghani or skunk, so many crosses were made with one of those two in them, they were proper breeder stock. I look at cookies the way that I looked at those. The old guard has been replaced and now it seems like over half of the legit proper strains have cookies somewhere in the genetic line. And it's odd too, because weed for me existing for a long time before cookies was ever a thing..... which only became a thing because it was the first "branded" weed strain.
The entire gene pool is being narrowed for better or for worse, but we really are loosing a lot of the genetic heritage. We're also coming up with some really awesome winners too. Once again, don't believe the hype 100% of the time.
