No one said that by opting-in to this behavior a Lisp program gives up
the ability to ask user questions via the minibuffer. I can easily
imagine programs that would like to do both.

??? How do you know which stdin input should go one way and which
should go the other way?

What do you mean by "at the same time"? If I have a stdin-process
active, we watch it via pselect and read from it using the machinery
in wait_reading_process_output and accept-process-output. During all
the time such a process is active, I see no way to also read from the
same descriptor bypassing the above mechanisms, in a way that won't
cause trouble on the Lisp level, due toe the basic inability to decide
which input should go what way.
