But it gets better. Given that anyone interested in performance installs caching of one sort or another, the overhead for your excellent method is near negligible. The more users per cached content the better. I would consider any such method that slims down the content delivered to all users, particularly at what seems like a small cost.

There isn't a practical way to detect if do_shortcode() is being called, so inside the shortcode handler you can just check if the scripts/styles have been enqueued. If they haven't then output an error message so that the theme developer knows they can't call do_shortcode() without also enqueueing the scripts manually, or telling the plugin which pages to load them on.
