When I use youtube-dl --write-info-json --write-description --write-thumbnail --write-annotations --all-subs --all-formats -o %(title)s-%(id)s/%(title)s-%(id)s-%(format_id)s.%(ext)s https://www.youtube.com/watch?v=PRjzqc2l6Yw it creates the metadata files (description, thumbnail etc) for each format, even though those things don't differ between video formats.

Here is a (possibly not very good) solution: Have a (option for) a separate, metadata-only, output parameter.
Example usage (-ov = output for video, -om = output for metadata):
youtube-dl --write-info-json --write-description --write-thumbnail --write-annotations --all-subs -- --all-formats -ov %(title)s-%(id)s/%(title)s-%(id)s-%(format_id)s.%(ext)s -om %(title)s-%(id)s/%(title)s-%(id)s.%(ext)s https://www.youtube.com/watch?v=PRjzqc2l6Yw

This is expected behavior. If you don't want metadata to be written for each format don't request it in the same run.

It was pretty stupid of me that I didn't think of that.
