I don't want multiplexed monitor sessions, at all.
I'm very happy to finally see them.  Finally one can run vms with
libvirt and *still* access the monitor for debugging and development
purposes.

Right, I like them for that purpose as well.  But not for ordinary control.

How do you want to differentiate? What further complications would this
bring us?

I'm not sure I understand your questions. Multiple monitor sessions are like multiple shell sessions. I don't think a control program should use more than one session, but it should allow a developer to connect to issue 'info registers' and 'x/20i' commands. Of course if a developer issues 'quit' or a hotunplug command, things will break.



Please no more async notifications to the monitors. They are just ugly
to parse, at least for us humans. I don't want to see any notification
in the middle of my half-typed command e.g.

If we can identify an interactive session, we might redraw the partial command after the prompt.

btw, why would a human enable notifications? Note notifications enabled on the management session will only be displayed there.
