So it's implemented in the wrong layer?

Is it a feature these days to annoy users?

Your link is a whole screen full of description what I need to do.
Seriously? The natural thing to do is -qmp stdio, and I don't read any
wikis for that.

It's nice that you can get some kind of usability by typing in long
network addresses or path names and hacking a rlwrap around it (didn't
know this one yet), but it's not stuff I want to deal with. It should
just work.

It tries to abstract QMP away from me. If I didn't want QMP, I'd use the
human monitor. Not sure if I can even get QMP shell to send a complex
command like 'transaction' correctly.

Anyway, even if QMP shell did what I wanted, I don't want to mess with
starting up another program and typing in network addresses. qemu used
to be simple to use, and that's what I liked about it.
