Will it be feasible to support a yaml alternative to package.json ?

JSON is really not a good configuration format and yaml would be beneficial in many ways:

• Supports comments

  This is the single biggest advantage. I find myself wondering so many times why a specific rc/alpha/outdated version was included in the package (instead of the latest stable), Some details about a script etc.

• Supports anchors

  Remove duplication between peer deps and dev deps etc.

• Multiline strings

  Useful for npm scripts involving commands

etc.
