Out of tree drivers have to be compiled on the target system (cannot 
ship a binary package), and occasionally break.

dkms helps with that, as do distributions that promise binary 
compatibility, but it is still a pain, compared to just shipping a 
userspace package.

Yes.  So your only motivation in rejecting the patch is to get the 
author to write the ring translation patch and port it to all relevant 
drivers instead?
