If I was designing the user experience for accessing content from a global information, entertainment, and commerce network that would be used by a large, global, non-technical user base, I would not use the current URL format.

I would wager the twelve character prefix "https://www."would make no sense to 99.9% of the users and should be the default for over 99.9% of requests they would be making any given day.

I am guessing Google has evidence that this is the case.
