525 are no technical obstacles preventing that, so it got enabled with a warning

527 mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
529 * support balance filters added/enhanced in linux 4.4

533 Note: due to backward compatibility, the range maximum for 'usage' is not
534 inclusive as for the others, to keep the same behaviour as usage=N .

635 * if nodesize was 64k, any metadata block was reported as crossing,
636 this leads to mkfs failure for example due to "no free blocks
638 * for other nodesizes, if the end of the metadata block was 64k
639 aligned, it was incorrectly reported by fsck
