Looks pretty dated. Docs refer to tests against jQuery 1.11.1 for example. Not registered with NPM or bower, no TypeScript alternative. Available forks look to have latest activity as far back as 2-3 years ago. Frankly, I think there is more than enough room in the space for a new empty library. Let's give empty a shot, yeah?
If you think empty would benefit from Vanilla, @matthewkremer has been open to pull requests!
