That's not good for the GUI, where the module won't have a stdin
(ideally, it will have been closed; if not, the module will hang,
waiting to read from whatever its stdin happens to be).

Requiring e.g. input=- has the advantage that GUI users are unlikely
to do this accidentally; choosing "-" via the file selector would
require that you have a file named "-" somewhere.
