.js in the footer. How to?

Yeah some plugins include their own stuff, but some also offer setting to disable.
Badly written plugins and themes cannot be helped.

If they are using gs asset queuing then you can probably manipulate the queue before the header, then output them yourself.

You can also somehow get plugins to add already loaded exclusions. window.jQuery || document.write etc.

Or replace the whole thing with require.js
