Idk it makes sense to me.

Like a lot of the rules are very fuzzy in their origin. The whole kosher business comes from a passage about "Not boiling a kid in it's mothers milk". I think most people would interpret that much more literally and you couldn't kill a child goat (kid) and boil it in it's mothers milk; and probably also extend it to other animals like cows. But I'd still think that killing a kid and putting a slice on cheese on the meat would be fine.

So if somebody is going to be obtuse with what you can do it seems like it'd be good fun to figure out all the ways around it.
