It was loong sleep, I was distracted by multiple things.

But I found
https://github.com/phillipberndt/fakexrandr

"You'll want to use this library if you have a multi-head setup, but a
crappy video driver which tells RandR that there is only one big monitor,
resulting in wrong window placement by window managers. Matrox Tripple Head
2 Go et al. are other candidates, where there really is only one big
monitor, but you'd want to split it anyway. *Another use case is to test
multi-head behaviour without having multiple monitors."*

====

works with x11 apps, not xcb-x11, but I think cingg exactly this kind of
"legacy" app?

found while looking at DRM lease (exclusive access to output) information,
should be in xserver 1.20 and later, but mostly used by SteamVR ?
