Well, it's obvious that from a spectacle point of view, the shorter the timer, the more fun it is to watch, but that doesn't mean that the game should be switched to a blitz format (although I wouldn't mind, I play with any timer). There should be some compromise between an outright blitz and a thoughtful, comfortable game.
Based on what I've seen in the streams, this option allows most players to show a fairly good game. Maybe not perfect.
If someone doesn't have enough time, they need to either improve their game or sign up for tournaments with a longer time control.
