Unfortunately when you score a page for speed things like jq and bs are counted against you when they are likely to be cached. Why don't any scoring systems (that I know of) able to take can asset popularity into account for things like this?

Just as interesting - I'd like to see stats on which CDNs offer the best chance of a warm cache for my visitors - and which versions of various libraries have the best chance of being cached.

If only the browsers would support caching based on the sha384 of the file then the script/css's integrity property would be even more useful and it wouldn't matter where you were serving it from.
