IMO this is not acceptable. For one, there's no precedent for removing a
qemu.conf option; IMO it's part of our API.

But the reason this option exists is so site admins can make listen
type=socket/socket= the graphical default, as opposed to a wide open
listen=127.0.0.1 that any user on the host can trivially access. VNC passwords
are known insecure, so locking down the listening mechanism is really the only
(current) way to secure VNC.
