In the case of a remote desktop or a VM the virtual screen is likely
to be made of gum and you do want to change its virtual size
dynamically to have a 1:1 relationship between virtual and actual
pixels.

This is exactly what won't work in a VM/hotplug/whatever context. What
the user said basically assumes a fixed dpi and/or physical size,
which is not the reality. You absolutely do *not* want to trust the
user and have the system adapt auto-dynamically to changes.
