The above method would be simplified if you just accumulated the `result`
object as you go... As in... initialize `result` before the `Q.all()` call,
then instead of, for example, `return { platform: p, version: v ? v : null };`
you would just do `result[p] = v || null;`. In the final then, you would ignore
the parameter and just return `result`.
