Only issue is what happens when the company that owns the search and has a dominant share of the browser market flags your site with the good old "warning: potential risk ahead" when people try to reach it directly? And buries the "I know the risk let me through" deep in the browser settings. Advocate for different browsers? Google is pushing web attestation in one form or the other. I wish the future would look bleak, because right now it's looking blue, red, yellow and green and it's worse.
