How can you use a CDN if you're also using a bundler/minifier?
Put another way, how can you bundle your app such that CDN-available libs are "dynamically linked" but your app and less common libs are "statically linked"?

Here's browserify's documentation about the matter: https://github.com/substack/node-browserify#external-require...
That doesn't seem related to the question of how to create a bundle that assumes that some libs have already been loaded with a previous script tag that pulled, say, jQuery from a CDN.
I meant this one: https://github.com/substack/node-browserify#bexternalfile
For something like jQuery you might also need a browserify shim. And now we're edging closer into some of the stuff this essay decries.
The other magic of CDNs (aside from the potential cache reuse that everyone is talking about in this thead) is that the user downloads files from a geographically closer server to them than your server. This is typically a huge speed up, and applies even if your JS files are 100% unique.
