Original issue's description:
> Android FRE: A New Deal
>
> Simplified as follows:
> - If '--disable-fre' -- skip temporarily
> - If a device hasn't been provisioned yet -- skip temporarily
> - If FRE has already been completed -- great
> - Otherwise, we start the FRE activity to see what to show.
>
> Note that it doesn't matter how exactly Chrome was launched
> (say, via the shortcut or via a VIEW intent), it always shows
> the full FRE unless it's a test or the Setup Wizard environment.
