Well, I'm not aware of any shipping non-512 byte block DIF devices other
than scsi_debug.

And it's not good enough to just fix it in DM since this is a hardware
parameter that needs to be queried and bubbled up. It can't be scaled
like the rest of the topology block sizes, it's wired in the
hardware. So I just don't see much point in trying to fix it now when
any ties to the logical block size will be severed in my impending patch
set.
