I'm not sure that 'dub-con' is really that easily containable with the examples you give above. Obviously, again, we're talking fiction only here.
I'm very fond of the entire variety of fic that deals with consent issues, from mild to noncon/rapefic. And the warning/advertising categories that float around are pretty diverse, and unfortunately very vague too - you have ambiguous consent, dub-con, coercion, non-con, rape... all, I would argue, potentially overlapping but not necessarily describing the same thing. People are interpreting these differently, and will therefore use them with different meanings, which doesn't help either.
My personal favourite are blackmail-type fics, which I would usually label as dub-con (because it's a more common fandom term), although coercion would be more precise. Though others would put it firmly under non-con. I don't think it's possible to come up with (or standardise) an interpretation that will be acceptable for everybody, because subjective interpretations will always differ.
Outside the sexual content, for example, I throw a fit (and boycott the fic) if a header spoils me for character death, and won't warn for it either apart from vague 'darkfic/disturbing content'. A lot of people, on the other hand, really want to be warned for this, and making everybody happy just doesn't seem to be possible.
