EDIT, to be clear: for Google search results.
Where will we see the setting, and is it still rolling out? I can see in my old Gmail account where I have "Ask before displaying external images" selected, so I'm presumably protected from AMP for now, but I would've expected to see the setting for AMP alongside it.
If the statement was, "I think AMP for Email is perfectly fine as is and doesn't need an option to disable." that might be something to call for disclosure.
To their credit, the Google Cloud product team does this religiously.
(toomuchtodo is indeed accurate that the Google Cloud team are top notch on disclosures.)
It's great when I'm on the light rail going through areas with patchy cell signal, but when an article's share buttons are broken because it's the AMP version it's a pain to figure out how to navigate to the non-AMP version of the article.
A couple news sources (usually technical ones) thankfully put a link to the non-AMP version somewhere on the page, but IMHO this should be automatically done for every AMP link opened.
That is available in the standard markup, so it should maybe just be added to the UI (in the ellipsis menu probably).
That's not actually sufficient. It needs to be opt-in, so I can search without signing in.
