Why have a $subscribeTo ?

https://github.com/vuejs/vue-rx/blob/master/src/methods/subscribeTo.js

Original Code:

export default function subscribeTo (observable, ...subscribeArgs) {
  const subscription = observable.subscribe(...subscribeArgs)
  ;(this._subscription || (this._subscription = new Subscription())).add(subscription)
  return subscription
}

I would recommend this approach instead:

export default function addSubscription (subscription) {
  ;(this._subscription || (this._subscription = new Subscription())).add(subscription)
}

It is simpler, cleaner a nicer way to not abstract logic away.
Then you can leave the subscribing elsewhere.

Some may just use native subscribe and then see the program works fine so forget to unsubscribe.
subscribeTo Implied that if full embrace the library, the library itself will take care everything
addSubscription didn't show that kind of sense

Why add ? Add to where? For what?

Or maybe call it addAutoUnsubSubscription?
