Regarding (1), this is a great way to distribute your language tooling. After a number of years using Atom, one thing that I've always wanted to see is a way to utilize multiple Atom instances all uniquely configured for a given use-case/language. For an editor that excels in customization, one thing Atom doesn't have is "profiles". I commend you for providing a Luna "profile" and I hope other languages/ecosystems consider using this approach.
