Didn't we go through this already and decide it was better for the user
to provide the TTY and tell GDB where to send the user? Just like we
do now for set inferior-tty?

It wouldn't be a big stretch to make this go for remote targets; GDB
would do the writing instead of the inferior. There'd be no input.

For Windows, if someone cared to implement it, you could probably pass
a pipe to GDB in some fashion. I do not know enough about Windows to
know how, or care enough about native Windows use of MI to figure it
out myself.
