I think this is a bad idea, and should not be pursued as a model (though it
has some apparent UI benefits)
Why?
The "devices" are seen by the system as separate devices, but in reality
they go down to the same hardware buffers... So, I have two "drivers" that
refer to the same piece of memory. There is no way for the system to know
this, so two applications can be writing to the same memory with no
knowledge that that is actually occurring.
This will lead to undefined results, and any bugs that occur due to this
will be considered user errors...
I would rather we dealt with the UI issues as UI issues and not "solve"
these at the driver level. If they are going to be solved at the driver
level in this manner, then the driver should do the extra work to ensure the
compatibility of their published capability with usage possibilities.
