Yea that one is fine and well covered in the blog post, and pretty easy to spot in light testing. I'm much more worried about the ones that are harder to spot until you have a false negative that turns into a real bug which would be caught by 1 tool and not another.
Can you add some examples of the things users care about that aren't well covered by this? I empathize with everyone who wants a feature comparison chart so they can be confident switching without unknowingly losing important safety checks.
