Are there actually any benefits though? I saw an article a few years back about how when loading jquery from Google's cdn there was about a 1% chance the user had it cached already. Since you have to have, the same library, the same cdn source and the same version of the library, it almost never is the case that the user has already grabbed this recently enough that it hasn't been kicked out. Plus the trend now is to use webpack and have all of your deps bundled in and served from the same server.
