The list is indeed very helpful and I was going to suggest adding a link to this on the Help page as it was already suggested and done.
I wouldn't recommend adding a new article to the "asking" section of the help center since it would just split useful information across several pages instead of condensing it in a single one, and it wouldn't be any more visible than the current Meta post is. Adding it to the "How to ask" article is not a possibility because that article is the same across the network, so it'd break it for other sites. And overriding it locally would mean more extra work if wanted to change the page, since we wouldn't be able to do so network-wide. And the Robotics Stack Exchange question checklist wouldn't be helpful for all the other sites across SE as the information is not suitable to the subject of the other sites.
So since we already have the link in the Help Center I think we are good here.
