Yes but no. - jquery.com becomes a central point of failure and attack; - jquery gets to be the biggest tracker of all time; - cache does not stay forever. Actually, with pages taking 3Mo everytime they load, after 100 click (not much), I invalidated 300 Mo of cache. If firefox allow 2go of cache (it's lot for only one app), then an the end of the day, all my cache has been busted.
