Looks like there is some traction to figuring out what to do about
this, whether it's a udev rule or something that happens in the kernel
itself. Pretty much the only hardware setup unaffected by this are
those with enterprise or NAS drives. Every configuration of a consumer
drive, single, linear/concat, and all software (mdadm, lvm, Btrfs)
RAID Levels are adversely affected by this.

I suspect, but haven't tested, that ZFS On Linux would be equally
affected, unless they're completely reimplementing their own block
layer (?) So there are quite a few parties now negatively impacted by
the current default behavior.
