I also completely disagree with your reasoning above.
The fact that many people believe or do some thing does not mean that “by definition” that that thing is not obviously stupid. E.g., inhaling glue, smashing things with one’s head, “the secret”, mukbang videos… the list is nearly endless.
Finally, “the principle” behind Prettier is also flawed when taken to the extreme they do. Paraphrasing my final comment on the github issue,
> It can be used to defend literally any styling choices, even ones that deliberately misaligned conditional branches with others at its logical level (much like prettier already is doing on a small scale in the example I referenced).
> Yes human beings are adaptable, but some things are easier to adapt to than others. It's objectively easier to spell Spanish than English, for example. It pays off to have consistency at a deeper level than simply making the same idiosyncratic choices each time an identical situation comes up.
