Not really, I know a bunch of companies that would fail lots on this list but are making millions. For a side project you'd probably be better off putting much more basic things like 'does it work on mobile', 'do the email addresses listed actually work', 'is robots.txt still set to disallow google' and 'have you actually gone through a whole order yet' on there. Seriously.
