You might as well timestamp it
There is a downside which I've experienced: if you want a triple-state boolean (null, false, true) then having a boolean column allows for that while a timestamp-as-boolean column does not (you lose the "null" value because that equals `false` in timestamp-as-boolean).Having a distinction between `null` and `false` can be handy for values that are optional or have a dynamic default. If it's `null` you know it is not explicitly set and could use a fallback value. If it's false you know it's explicitly set as false.A simple use-case for this is when a user can leave the field blank. This is impossible to model with only a timestamp-as-boolean.Another use-case is dynamic defaults or fallbacks, e.g. `hidden` of a folder where if `hidden` is nil, you fall back to the parent folder's value.TL;DR a boolean column actually has 3 states, a timestamp only has 2. Article makes a big deal about there not being any nuance about the fact that a timestamp is superior. I disagree, because you go from 3 states to 2 states, there are cases where you'd want a boolean instead of a timestamp. Ironically OP missed this nuance (or they'll pull a no-true-scotsman).
