If this double by an unlimited hand when a pass wouldn't be forcing, over a rebid by an unsupported overcaller/preemptor, isn't penalty, what is?
First of all, the fact that partner is unlimited and pass is not forcing is not a reason to play penalty doubles. On the contrary, these are reasons to play takeout doubles.
Few people play penalty doubles after a simple overcall, even though they are unlimited and their pass is not forcing. However, if the opponents come in after a 2/1 auction, double is often played as penalty. The same is true after 1NT - Dbl* - Rdbl, where redouble shows a good hand and forces the auction to 2NT. If the opponents bid, it is possible to play takeout doubles but many play penalty doubles. However, after (1NT = 12-14) - Dbl - (2H) most do not play forcing passes and then it makes more sense to play takeout doubles.
Having limited yourself also makes it more likely that double is penalty. If we pass partner's 2S but the opponents balance, double is penalty. Why play takeout doubles when we have already found our fit and have no interest in bidding game?
In the auction 1H - (P) - 1NT - (3D) - p - p - Dbl, I would argue the double needs to be a penalty double. The 1NT bidder has limited himself not only in terms of point count, but also by denying 4 spades or 3 hearts. While it is possible that one could come up with a hand where responder might want to make a takeout double, a penalty double must be more common and useful.
After (1S) - p - (1NT) - p - (2S) I think that double should be played as penalty. By passing initially we have limited the hands we could have. Penalty will both be more common and more useful here.
Your final point is that the opponents have shown that they have no clue by first bidding 2H and then 3H. I don't see this as a good reason to play penalty doubles. In my experience, people who bid like this often have more hearts than you would expect, not fewer. In terms of defining rules this is also messy, should double be penalty when it is obvious that the opponents are bad, or only when they make a really stupid bid? I'd rather define my doubles in terms of what we have shown or denied.
Please note: I am interested in boring, bog standard, 2/1.
