In GURPS rules and examples are both subject to GM approval for the setting. "Dislikes carrots" wouldn't qualify as a perk in a GURPS: Star Frontiers game (there are no carrots) but might be a actual disadvantage in a Bunnies & Burrows game (where it might be a combination of Restricted Diet and Social Stigma).
