Also browsers should put up a warning then a site all of the sudden have changed certificate/ca. Yes, it would give false positives when sites change their certificates due to expiry date, but the algorithm could include expiry date and also moste sites probably change their CA more seldom than they change their certificates so stronger warning could be issue then.
It shows you each site's certificate when the browser first encounters it, then shows you a side-by-side comparison if the site ever changes its certificate.
