Let us not say people are crazy when there are alternate narratives
I actually find your explanation even less believable than this being a symptom of a crazy person (which I don't necessarily believe it is either).
To some nonsense about pineapple on pizza? Are there any adults left?
If there were no facts in evidence, it your alternate possibility would still not be plausible since there's no reason the person wouldn't hide the checkbox if they didn't want to delete it but there's also no reason not to just delete it since removing it from the client is as much of a code change as changing the text.
Developers on WordPress.org have stated that the value was not stored, and still is not stored. Matt also said he didn't care if you checked it or not.
WordPress isn't as legacy as those platforms for whom "too hard to change the functionality, just change the text" is common.
