How is something like "Use CSP without allowing unsafe-* backdoors" in any way educational? If I'm a newbie web developer, even coming over from embedded systems, how do I know what CSP is? What do I use CSP for? How do I start with CSP? What do I do to configure CSP? What does CSP even stand for? I don't know, it wasn't even defined!
Basically, this is a useless listicle. If you know anything about web security you get nothing from it and if you don't know anything about web security you still get nothing from it.
You are right: checklist is not for education. If you don't know how to implement one of those items, you need to go learn. The checklist itself is still valuable, even to a seasoned security developer.
A checklist will not teach a pilot how to fly and land a plane, but it's value is not zero..
I don't need to get started and I don't need that link; I, personally, know how to develop secure webapps. I am criticizing your listicle for being useless because it is. Your "educational" resource is not educational for anyone.
Basically, this is a useless listicle. If you know anything about web security you get nothing from it and if you don't know anything about web security you still get nothing from it.
