Indeed, and also now with agents everywhere the docs can be updated and checked more regularly. If it's in the wiki, you can clone it locally and put an AGENTS.md line informing of where the docs are, but it's still a separate repo to deal with. Credit where due, it was a revolution (even a godsend) in it's time, but at this point I agree a /docs is better.
im having trouble connecting the dots here. How does adding the friction of code review reduce rot?
You can spot a code change without a docs change or vice versa
