The number of options that prettier exposes (despite boasting about being "opinionated", i.e. disregarding the user's opinions) suggests that there are people with different aesthetics or accessibility needs who would not consider one style to be always correct.

IMHO we're about 10 years overdue for committing a canonical representation of that AST to version control instead of treating a particular serialized visualization of it as the single source of truth (and spending countless hours debating which format is "good enough" for everyone in every situation).
