I think you're being unfair. There's nothing bug ridden or inconsistent here, just a simple categorization system that looks like it would be pretty decent for small to medium sized projects.

It's also not informally specified. The shared link is literally the specification document. It's written in a kinds of informal style, sure, but that's a different kind of informal - Greenspun's informal means "not written down at all".

Uncharitable. The fact that this is called "Johnny Decimal" is a nod to Dewey Decimal in the first place

I suspect that rsecora was going for humorous parallelism rather than meaning any dig at the linked project.

This is exactly why the name was chosen (I'm Alex).
