I think it's more than just a kernel maintainer stepping up to test, there really needs to be some in-kernel justification for the vfio-platform driver itself. If it's only enabling out of tree use cases and there's nothing in-tree that's actually independently worthwhile, I don't really see why we shouldn't remove it and just let those out of tree use cases provide their own out of tree versions of vfio-platform.
