I'm in the "no precision platforming" camp. The concept of the game is about being clever, solving puzzles, and exploring every nook and cranny. Precision platforming is a pure twitch skill, and the mere presence of it excludes non-hardcore players.

(It's especially bad when a switch happens partway through the game, like when Hollow Knight suddenly turns into Super Meat Boy after maintaining a high but reasonable difficulty until that point.)

I guess my viewpoint is that precision platform players will generally prefer to play a game that's all precision platforming, while anyone else is likely to be turned off by its presence.
