It might be a personal opinion, but I do not like this at all. A cert error now looks way too similar to other connection errors. Other errors you cannot bypass, but cert errors you can. This change means I am going to go cert error blind and assume the site is just inaccessible. The older loud yellow alert made things easy to differentiate.
In 99% of connections, a certificate error should be connection failure. In the 1% where it's the sysadmin forgetting to renew or a dev using a self-signed cert, you can still bypass.
