What part of "instead of checking whether there is any difference, check for a specific difference" is specific to is_deeply and not general test logic?

well you spoke specifically about is_deeply

I think my demo of a workaround shows what I wanted, since all tests are returning a boolean result.

I only mention is_deeply in this sentence:

You won't need is_deeply since you don't need to check all elements.

In what way is "You won't need is_deeply" specifically about is_deeply? The approach of testing for a specific known difference in your prepared data is a general approach that works for your cases, or at least you haven't shown a counterexample.
