Say I have a web component that uses jQuery and I want to distribute it as a packaged component.

I need a way to ensure that the jQuery library is available on or after the page loads, but I also want to check that the containing html page, or another unknown component that may reference jQuery hasn't already added the library to the page.

At the moment the best example I've seen is this

It would need a little tweaking, but I was wondering if there were any other best practices.
