I think we agree more than we disagree on how to go about designing a schema, but that my narrow disagreement is that I think a.) timestamps and enums are better choices than booleans most of the time (without judging anyone who uses booleans to be a "terrible engineer", it's not malpractice) and b.) that's a legitimate trick of the trade rather than something "mindless".

I would agree that throwing a table together based on Twitter vibes without actually designing it will only work like a stuck clock, but I think that goes without saying. I kinda disregard opinions attributed to nebulous Twitter posters and not specific people. I think when you conflate people's opinions together like that you reduce their position to a caricature. If you poll that group of people almost all of them will have a more nuanced opinion.
