we don't have a smart way to migrate only the default theme, the way the migration system work is either we migrate the key value or not ... there were hundred of gtk2 themes out there and an UI to set those so lot of users have a custom theme, upgrading the theme has no equivalent for gtk3 and migrating the value would create issues, it's safer to reset the theme
