TL;DR: How do we enable embedded-language-formatting in non-JS files but keep it disabled in JS files?

Currently, the embeddedLanguageFormatting option is off by default.

This is because our embedded formatting for JS/TS files is not fully implemented. See #15180.

But at the same time, we now support non-JS/TS files, and embedded formatting for them is handled by Prettier, so it should work.

Because of the default off, a few issues have already been reported:

• oxfmt: .prettierrc is formatted with trailing comma #16673
• formatter: Diff with Prettier on angular multiline interpolation #16702
• formatter: fail & empty lines added when character immediately after multi-line template expression in .vue files #16945
• formatter: Incorrectly formats nested code block #17062
• oxfmt: non-js files support #15899 (comment)

I think we should change the default to auto now.
But I also prefer to keep off for JS/TS files for a while.

So..., how about

• adding another flag experimentalJsEmbeddedLanguageFormatting to disable embedded formatting only for JS/TS files?
• Or add our own variant on embeddedLanguageFormatting: auto | off | disble-oxc?
• Or should we just disable the feature itself until we have finished with the JS/TS files?
  • I now tend to this
• Or just change default to auto
  • incomplete but works
