Makes me wonder if it would make sense to have it built-in in browsers?
<node>.querySelector(...) and <node>.querySelectorAll(...)
If all you're using jQuery for is grabbing nodes from the DOM and attaching event listeners AND you don't care about old versions of IE then...

In a nut: querySelector[All] requires IE8, addEventListener requires IE9.

Perhaps if it was implemented as a resource="jquery-1.8.0" attribute on the script tag, allowing browsers with a copy to load that instead of hitting the server.
