I have a somewhat severe nut allergy, and even I think this is stupid. How big of a buffer zone is required? Would they have to stop serving nuts in the J cabin because I'm there?
The only accomodation I'd like AC to make for me is that I can get a snack without nuts - it is very rare that inhaling nuts ever gives people reactions; reaction comes from actually consuming nuts. I hate it when I am in J and I can't get a snack because all they've got is a package of almonds and the FA doesn't even want to get the salted snacks they serve in Y (although I'd much prefer a cookie or something nicer than the standard Y snack).
