I could sum that as “UA does not have enough information, so the dialog is scary.” Over time, our browsers have evolved to show color codes that reflect some perceived security: green if https and the certificate could be verified, red if https and the certificate could not be verified, neutral if http. Consider now a web site that choses to use a self-signed certificate. If it advertises "https" URI, the browsers will flash red until the users do something really scary. If it advertises "http," then there will be no encryption. It seems that we need a third option, something like "http opportunistic," in which the browser knows that it does not need to put up a warning if the certificate is self-signed.
