I don't know, I think its generally bad form to engage in scorched earth tactics unless your opponent broke a NAP or something else like that. It just smacks of bad sportsmanship to me, trying to degrade the victory of someone who defeated you after the fact. It's only "wise" from a games theory POV if you're trying to influence future games by what you're doing here, which also seems rather poor sportsmanship (as in you're trying to give yourself an advantage in a subsequent game that has nothing to do with that game).
