subtitle.language_priority and audio.language_priority prepend to the CLI languages, so the named languages sort first and nothing is filtered. --exact-lang now applies to the sorts too, through matching_languages, which follows the same RFC 4647 rule as Tracks.by_language and ignores invalid tags.
