I think that "remaining" = "all" - "completed", so that's the filter that will give you what you want for "all." I think it's handy to have both that and the true "all" filter options (e.g., when reviewing a project's overall progress).

As for the flagged issue, I'm more in agreement. (At least as I am trying to use it,) a flag seems to me like a metadata attachment to a task - more like, say, a start date - rather than a status of the task - like available, completed, etc. Philosophically and functionally I would much rather have "flagged" be a selector on the group and sort filters than on the status filter (as I've said elsewhere).
