Yes, that's probably useful.  I've also been wondering if we need a
kernel command line interface to enable quirks for given IDs, similar
to what SCSI has.  With the amount of amazingly crappy consumer devices
our number of quirks will keep growing exponentially unless we can finally
get the NVMe interop group to actually test for these kinds of real life
bug instead of silly crap like status code precedence.
