Those old enough to remember roll crimped, paper shotshells will remember the too frequently scattered pattens, and the "blooper" shots, caused by tipped flat wads, and the bore fouling from lead contact, before the power piston and star crimp came into being in the late 60's. The pellets, having flat sides from bore contact, scattered the patterns a lot. Given lead or bizmuth pellets, the 3" 20 ga of today is every bit as "good" a goose load as steel shot in a 3" 12 ga (which is rated as being "good enough,but nothing great". Still a LOT better than the 2 3/4" 12 ga, with lead, when using the paper hulls.
Those paper hulled 12 ga's sufficed to kill literally trainloads of waterfowl, so today's 20 ga can do the same. you lug around a 12 ga and put up with the weight, bulk and recoil of the 12 ga, for nothing, basically. For nearly allof what a shotgun is used for, rabbit, squirrel, upland birds, the 20 ga has plenty of "reach", even if you use the 7/8" oz shell. When you shred a man's chest with buckshot at indoor distances, it's not gonna matter if the load was 24 pellets of #4 Buck from a 12 ga, or 20 pellets of #3 buck from a 20 ga. It's still gonna tear a bloody rathole in him.
