It's true that moderation comments break the guidelines by being off-topic locally, but they help the site conform better to the guidelines globally.
I post those links so readers know why a story is being treated as a dupe, and so submitters see examples of how to search for this before posting.
This case is particularly clear: the project (which I don't doubt is excellent work, by the way) has had major attention twice recently, including as late as last week. Normally we look for just one major post in the last year. Please see https://news.ycombinator.com/newsfaq.html.
Getting our doc site live is a huge milestone for us. Maybe not necessarily front-page worthy, but I didn't submit it :) Our biggest feedback last time the github repo was posted was a lack of guides. I hope newcomers find these helpful. Our guides and howtos are still a WIP, but there's lots of good info already on getting up to speed.
