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.
