Not that the episode count should necessarily be halved for all of them but the following shows would only benefit from having less episodes.

Not really. Its an episodic SoL. It only benefits from having more episodes. If you start to feel burnt out, you watch them more sporadically.
Besides, the anime original episodes were the best part of the show.

Any show with a large cast of characters needs to have more than 1cour in order to fully flesh out the cast.

Season 2 was perfect and you're an idiot.

K-On is unironically mankind's greatest cultural achievement and the pinnacle of our existence as a species.

Shinsekai yori

It basically took the first entire cour for anything resembling an overarching plot to appear and most of the things that happened happened in the latter half of the second cour.
