Not sure about "generally", but it's a good principle to decompose a functionality into a "batch-only" part and an interactive wrapper. So we probably wouldn't consider all such cases as bugs, but if a particular case is problematic, you should definitely request the change (which we may sometimes reject, of course, typically if it would require too many/ugly modifications to the code).
