I think that can be scary for the wrong reasons. Like a whole part of the web will be marked as "non-secure" where it should be marked as "non-encrypted." Security-wise, MIM (Man in the Middle) attacks using HTTP are a fraction of the real security threats (Phishing that can use https!, Keyloger, Malware, Browser Vulnerabilities...) It will give too much weight to HTTPs websites or too little to HTTP websites. Moreover, SSL certificates are expensive!
