idk I feel like this is one of those unintentionally neat bits of worldbuilding that sometimes crop up in harry potter, reminds me a bit of the moral panic over ninjas that led Teenage Mutant Ninja Turtles being censored in the UK (swapping Ninja for "Hero") and the laws that still specifically call out things like samurai swords and nunchucks. I can totally imagine in the world of harry potter some gang or something terrorising everyone with those three specific spells and the government going right well you can't use those spells then, problem solved.
