A very significant portion of virt-manager users will not want that
kind of behaviour, even for local VMs. Which means you'll end up having
to add yet another checkbox preference to turn this off & on, then
people will still argue about whether it should default to on or off.

Again the user interaction model you're describing here is one that
is satisfied by GNOME Boxes.

It isn't clear to me that we want to give virt-manager a split
personality where it works one way for remote VMs, and then tries
to emulate Boxes when using local VMs, which is what your proposals
pretty much imply.
