If you do, would love see experiments on that. I do wish NPM would start adding badges or some other meta data to packages that signify that a module has constraints like: - No native code - No module state (No multiple singletons, and easily load variants of a module) - Pure installation, aka no build steps and is fully cacheable via hashing/immutable module patterns - Is all pure functional - 100% code coverage - Etc.

Hmm.. is it still available as a configuration option somewhere? I couldn't find it on the site.

I'm a huge fan of bundler - it's dependency heaven. I'm also a big fan of the rubygems repo. It does not allow changes in released versions.

Even without symlinks it's a much needed improvement in the javascript ecosystem

This is something I hope to work on over the next few months. It's a priority for Ember :)
