Why not, instead, show an ellipsis in place of the majority of the subdomain leading up to the domain and increase opacity of the domain compared to subdomains and the pathname.

This is similar to what happens when the path is too long for the omnibox, but simply the effect of putting the domain as far left (in the omnibox) as possible.

i.e. instead of seeing:

[ www.mybank.com.credicards.wt3_segment_secure.login.html.evil-site.com ]

You see:

[ ...html.evil-site.com/ ] (where "...html." are semi-opaque).

I mocked up what I'm suggesting here: http://remysharp.com/2014/05/04/on-chrome-hiding-urls-to-pro...
