Don't you think that it would be better to get rid of usernames in UI? They only provide unique data for fingerprinting and do almost nothing useful on a single-user system. Wouldn't it be better to simply have a default name like "primary user" or "main user" for the first user and skip one step in installation process? Also it frees you from typing a username on login for a single-user system.
