As always, the internet has already generated a counter example to your rule:

If their goal is to make their product listings useful, they wouldn't include that as a shoe.

It only means that either category is okay, not that it should be allowed to be changed.

But I don't think this restriction would fix all the issues where listing in the same category is swapped.

I like that "Spy Cameras Mall" and Spy Camera Small" work as ways to read the address.
