$published = $flag->enabled_for_user(); // will return false until `init` because current user ID is not known before `init`. 
$published = $flag->enabled_for_user( $user_id ); // will work, since we don't need to lookup the current user. 
$published = $flag->enabled(); // will vary - if the flag has a forced state or published, this will work as expected. If none of the other rules apply, it fallsback to checking current user, so will return false before the `init` hook because we don't know the current user ID.
$published = $flag->enabled( $user_id ); // As above - will work as expected.
