Oh, this seems to be more or less completely ignored when selecting subtitles, though some players will at least list "English (forced)" or "English (default)" &c. when selecting a subtitle. Quite a pain with dubbed foreign-films when the subtitles are used for translating on-screen text; you really want the forced subtitle in that case!
You almost always want to see what's in the forced subs; but if you're reading a different language then it has to be translated first. Also compression and color/HDR mapping prefers the text be separate from the image.
