I assume you're referring to the custom data associated with the 
resource?  I think you're right, since they could instead create a 
shared memory handle which they use to store a KMT handle and the 
resource desc.

If you're referring to the whole patchset, I think we need to at-least 
export some of the file descriptor<->handle functions in ntdll so we can 
turn the FD provided by VK_EXTERNAL_MEMORY_fd into a handle for the 
win32 extension.
