Discussed this at the jQuery team meeting in Amsterdam: The spec is still changing a lot (within whatwg and draft pages on github), so we'll wait for it to ship, unprefixed, not behind a flag, in stable browsers first.

Once that happened, we should change/fix our implementation to match the spec (and shipped implementation).

Can use .pipe() to continue using any jQuery-specific functionality.
