It looks like this addresses the biggest issues people have with npm's CLI, and it's coming from such huge names: Facebook, Google, and Tilde. Reproducible builds are a _huge_ issue, and this gives you that. Looks great!

One interesting little tidbit I found from diving into the source:

  https://github.com/yarnpkg/yarn/blob/master/src/constants.js#L15

  https://github.com/yarnpkg/yarn/blob/master/src/registries/yarn-registry.js

It's not mentioned in the post, but looks like they're running their own registry as well...

Oh! And open governance: https://github.com/yarnpkg/rfcs !
