Indeed: one of the first things I do on a new android phone is activate developer mode specifically so that I can set the animation timescale to 0×.

Which the majority of people think is a horrible experience. There's even a sibling comment in this thread pointing that out: https://news.ycombinator.com/item?id=48518721

Unless you can back that up, "Majority" is something you're making up. It's a guess.

It also doesn't matter whether it's true if the majority or not- "Instant transitions are only good in theory" is not a true statement. Instant transitions are good in practice for many people and that has been true for decades.
