Does Chrome send back (anonymized) data about usage? Or are there instrumented versions of Chrome/Chromium that do do this? I wonder what the usage numbers are for how often you focus on the URL bar and change it within one tab. I notice in my own usage, I pretty much ALWAYS open a NEW tab to go to a new site and never touch the URL bar, so compacting it or hiding it behind an extra click seems like good UX design if it's backed up by usage data.
