Client persistence across GPU hotexchange

Good day, folks!
I'd like some light to be shed on the general area of GPU
hotplug/hotremoval, and in particular, on how this is supposed to affect
What is the state of multi-card output?
Is it possible to have drm_outputs replaced with (non-GL) clients surviving?
A specific scenario I have in mind is:
- weston initially starts with an accelerated DRM device (#1)
- some fairly pedestrian (plain GTK/Qt) clients start
- a dumb framebuffer DRM device (#2) is hot-added
- the accelerated device (#1) is removed
Is it possible to even express this with the current infrastructure?
What is the estimate for the survival of the clients, if so?
