For my use case this would not be harsh. A running Emacs will explicitly
opt-in to use the special make-stdio-process to read from stdin. This
special process will only be used by external worker Emacsen controlled
from the main Emacs. In that scenario the data flowing over stdin-stdout
is tightly controlled (IPC protocol). There hopefully won't be spurious
read-from-minibuffer calls.
