Yes it is. Reminding somebody of this feature is useful to somebody, even if it's not completely relevant to the topic being discussed. Calling out a supposed tautology is the opposite of useful: it helps nobody and just clutters things up.

Yeah, it's especially useful in that case. Useful to attackers, because someone "helpfully" showed up with "reminder" that reads like a suggestion to post these specific secrets (or any other Algolia secrets that other HNers might have come across) in the open out of some misguided belief that doing so will invalidate them.
This has to be one of the dumbest, most reckless threads to have been posted (and so vociferously defended) on HN.
