I don't see a lot of external CDN script (like cdnjs) use in the real-world anymore. That's sort of dated compared to bundling and using something like S3. Ideally, these days you'd still minify, but your *.html files could plainly include scripts, and the server would read the resources to be sent, and send them all over the same stream, rather than forcing a client to open multiple connections.
