That's why the GFML catering option is so useful on those flights that offer it. The caterers are essentially saying that they know and understand the seriousness of the problem and the rules and are giving you something that complies with the rules and that has been kept separate from other food.
But, as HNL and janetdoe indicated, it's possible that the caterers aren't as careful as one would hope. (At some point, you have to draw lines as to who to trust.) And as Efrem pointed out, I can't always rely on being on the same flight as originally planned. Which means that I'll be grateful for the GFML when that's an option, but I should always be prepared.
