I don't really know at this point. We talked about it a bit on IRC,
but there is no consensus yet on what should be responsible for
creating display devices and allocating LUIDs. I imagine Wine graphics
driver should be involved since we need to enumerate available Vulkan
physical devices.

The patch was submitted mainly to show a potential storage for display
adapter LUIDs. We would like to expose stable LUIDs in OpenGL [1] and
Vulkan [2]. When we have stable LUIDs in OpenGL and Vulkan we will be
able to match OpenGL and Vulkan devices, and expose stable LUIDs in
d3d9 and dxgi.
