Isn't the canonical URL in a meta tag a requirement of AMP? Edit: to clarify, i find this part of the article quite odd (assuming my understanding about canonical URLs in a meta tag is true): > What’s more, AMP URLs aren’t standard — an AMP link for say, The Verge, looks different from that of another publisher — so Apple is presumably doing some work under the hood to find these canonical URLs.
