Adults have trouble enough to grasp the concept of a deathly allergy to a common foodstuff, let alone kids. I think that's the reasoning behind this kind of ban. Not "breaking the rules" but causing harm to other kids because they don't understand the dangers.

For instance, the following is a news item about a kid in a London school with a dairy allergy who died because his classmates flicked a bit of cheese at him as a joke:

A schoolboy with a dairy allergy was left gasping for breath and shouted “I’m going to die” minutes after a fellow pupil flicked cheese at him, an inquest has heard.

Karanbir Singh Cheema, 13, known as Karan, went from “absolutely fine” to unconscious in under 10 minutes after the incident at William Perkin Church of England high school in Greenford, west London, on 28 June 2017.

Karan, described as “so bright he could have been anything he wanted”, died 10 days later at Great Ormond Street hospital.
