This article is almost jumping the shark. It's fine to say it's in the constellation of things that help document code, but the end where you're starting to limit the tests you can do to highlight an ideal, for example, the "atomic" bullet, that's where you're now doing things for ideology, not really for their utility. A similar thing occurred with function purity, etc, etc.
I don't know who this helps but if you're a young developer, always beware what you read on substack about how you should constrain yourself. Take them with a grain of salt.
