Also for what it's worth, it also works for multiple device Btrfs volumes, all profiles supported by GRUB2. For me GRUB fails to navigate Btrfs for RAID0 if there are 5+ devices. Single still works, oddly RAID10 still works. So some regression is needed to figure out what's going on there. May be a bug, but honestly it's still pretty cool.

Also to test is if installing grub to each device, in a multiple device raid1 or raid10 volume, still allows it to be bootable with any one device removed from the volume. I think it'll work.
