Engines definition excludes node 6

[shahkashani]

I may be mistaken, but this module seems to work fine with node 6? However, when I try to install it with yarn, I get the following error:

error usus@1.6.0: The engine “node” is incompatible with this module. Expected version “>6".

The engines definition in my project is the following:

  "engines": {
    "node": "^6.10.3"
  },

Is this just a matter of changing the package.json in this repo to allow 6? It would be nice to not force all our engineers to use --ignore-engines!
