For that we would have to parse it first, which has some ugly corner
cases on id clashes ...

All I wanna do here is keep it alive for the existing use cases, without
support for multiple displays, with minimum effort.

Should we need support for vnc config change in a multiple vnc server
setup a new qmp monitor command should be designed for that.

cheers,
