Google, on the other hand, doesn't use the Expires header, they

use the Last-Modified header. This means that instead of the browser
just outright using the cached jQuery library, it first has to ask
Google if the file has been modified for *every* page on your site
that
uses the jQuery library. All of those unnecessary HTTP requests (one
per page) add overhead and degrade performance. So the irony here is
that you will get BETTER performance for your users by hosting the
jQuery library yourself and using the Expires header.
I revisited this and Google has switched to using the Expires header
for the hosted JQuery library (and probably all the others as
well). Not sure who at Google made the change, but it's a huge
improvement, thanks!
