I appreciate the point.
But,
If this was a website that made tangible revenue via Sales/webLeads, I suppose the tone of this discussion might change? ;)
One wouldn't then, be happy to rely on a 3rd party (Google/browser design committee) to tell users what to do.
Just saying.
BTW, I just noticed my 'reading' browser of choice (Opera) has a URL completion config option in Preferences>Advanced>Network>Server Name Completion. Can't say it works. Maybe a restart will fix it.
