I get what you mean, but I think it’s questionable whether this is global. I agree with the applications you’ve mentioned, but I can see other circumstances where it doesn’t hold.
Sometimes you may avoid certain courses of action IC because you know that it would have undesirable OOC effects on other people. For example, you may know what degree of physical intimacy another player is happy to have OOC (or more importantly, not to have), and I think you should use that knowledge. You may know whether it’s appropriate OOC to introduce adult themes into a game, and use that knowledge.
Frankly, I’m of the opinion that there are no global cross-larp rules. It all depends on the social contract between the participants, which can vary wildly between larps.
There’s a school of thought that everything in a game is OOC, and some things happen to be IC as well. I give that a lot of credence. OOC knowledge of actions that might break the social contract that the game runs under should be allowed to influence your IC actions in the game. Because everything that you do IC in LARP, you also do (or pretend to do) OOC.
