I am one of those old dinosaurs who used to play by the 2-point rule. I originally bought my RGG Carcassonne back in 2000 or 2001. My stuff is so old that of most of my large expansions have the darker grass (what I now call "medium" green), and my base game has a 70-space scoring track. (It's actually a rather illogical 71 spaces, but that's beside the point.)
Having said all that, I say good riddance to the 2-point rule. Its elimination was a good thing, as was the change in farm scoring. There are other reasons not to spend your turn on a 4-point city, and if it does happen on occasion it's certainly not the end of the world.
