[Waffleloffle]

it harms the general player experience because it muddies the waters between real antags and people who are just playing antag-adjacent characters. like sure you may not be going out there and directly self-antagging, but there's like a weird meta element to it where people will have to make a mental note that so-and-so in cargo is a Nice Vampire so little timmy the new secass needs to be told to ignore when they're pouring blood bags into their mug and drinking it

like... this game isn't just a chatroom where everyone brings their own oc and plays dolls with them. it's got mechanics. and social deduction is at the core of how a lot of those mechanics are designed. what you are asking for here is something that, by its very nature, flies in the face of all that
