Support for non-seekable streams would certainly be very desirable from the API user's perspective. In GraphicsMagick we currently must create a temporary file if the input is from a non-seekable stream. Doing so is painful. Unfortunately, libtiff supports random I/O of tiles and strips so it seems very difficult to support streams unless a temporary file is automatically created under the covers.
