And how now in package.json to set engines for io.js and node.js at the same time?

Question

Node.js

And how is it supposed to be written in package.json now?
It would be logical like this

"engines": {
  "node": ">=0.10.6",
  "iojs": ">=1.0.0"
}

but I did not find any docs, articles or examples that already had two engines set in them.
