It's good if it plays some role when the content quality is similar between results. Some pages are so slow or obnoxious that I'd almost rather not get the information at all, than dreadfully waiting for ads and pop-up-modals to load. Perhaps ranking is the wrong tool, but it would be nice if I could know that a site is bloated before clicking the link. AMP lets me know that.
