> You'll only ever retrieve Google AMP cache results from the Google search page
Uh, I keep seeing Google AMP URLs shared on social media, emails, etc etc. Which is quite annoying :(

If you click the browser share icon, or trigger the browser native share intent, the origin URL will be shared, not the AMP Cache URL. Only if you explicitly copy the URL bar will the AMP Cache URL be shared.
The Signed Exchange spec that AMP has offered sites for a year now allows them to have their own URLs displayed in browsers that support it. In that case, the google.com URL will never be displayed and thus can't be accidentally shared.
All AMP documents on the AMP Cache contain `<link rel=canonical href={origin url}>` and Google recommends that social media prefers the canonical URL. This is useful outside of AMP as there are often multiple URL variants for any article. The sharer and sharee may not ideally get the same version. As an example, a mobile vs. desktop article.
An AMP page can be identified by examining only the first few bytes of the HTML. The `<html>` tag will contain either the `amp` or lighting-bolt emoji attribute, ie: `<html amp>`.
Technically an AMP document must pass AMP Validation to be truly AMP, so there are documents that match the above condition which aren't valid AMP. There are multiple ways to validate. A starting place is https://validator.amp.dev/
Also, "the google.com URL will never be displayed" is a world with an internet I don't want to be a part of.
Also, others might share an amp link from their mobile devices, which I then end up clicking in a desktop slack/mail/messages app, and there we go again with the amp virus even on desktops.
