As I understand btrfs, "hot spare" is a meaningless term. Given that btrfs understands the concept of a filesystem spanning multiple drives, if a drive fails underneath it any files which have been declared as "mirrored" and have a copy on the failed drive, will have suddenly become "single copy" so the file system needs to replicate them onto another drive. And I'm guessing losing a drive would immediately trigger some sort of filesystem scan and rebalance - be weird if it didn't.
