We are working on a direct path from AMP pages loaded from Google Search to the canonical to fix the link issue & sharing will use the canonical link where technically possible.

How about a similar lightning bolt for sites with < 1s loading time and no popups that just show the content?

In that case it should be relatively easy to provide an AMP version of the page. If you already offer a lean page, it's not much to change.

Adding AMP will actually make the pages heavier in many of these cases.

It seems counter-intuitive to slow a page to get a lightning bolt.

While you're at it, why not add "straight links" to normal Google results so they can be copied as well? The current situation having everything be a Google referral link is a pain in the neck and users go out of their way to avoid copying those.
