People conflate opinionated formats with autoformatting for some reason.

An autoformatter removes 99% effort from formatting code, and that includes code actively being worked on. Autoformatters are incredibly useful.

A standardized format removes effort spent learning to read a new format. That's an hour per format at most.

I don't see any good reasons for an autoformatter to enforce a standard. A standard would work just as well if defined as a specific configuration.
