That has nothing to do with this, I don't think you understand this vulnerability. You can see which certificate authority issued the cert, so you can see if the suddenly the site started using a vulnerable cert provider and thus know that it is compromised. Note that the same attack is possible right now, the only difference is how your browser displays it, you can just install a plugin to get back the original behavior if you want. So this in no way prevents you from secure browsing.
TLDR: If you are worried about security you can always install a plugin to get back the old behavior. This just says that browsers should be able to trust them, not that you have to configure your browser to trust them.
