I think it definitely needs to include ZeroTouch nodes as a lot of packages are made with these. I would also suggest to perhaps work your way down the package manager list with the number of downloads being considered as this would include packages that users rely on frequently, and not just the ones the uploader had installed at the time.
Also, this website only offers search? Would there be a way to allow for menus like https://dynamonodes.com/ has been doing for a while?
