This won't answer your question (not sure why missing doesn't work anymore), but you could wait for the replacement and then run "btrfs replace start 1 /dev/sdd /mnt", where 1 is the devid of the missing drive (dmesg will tell you) and /dev/sdd is the new drive. This way, the drive will keep its devid, which may be useful if the ids are used to identify the drives (mirror will still have id 1 as first drive and id 2 as second drive as opposed to 2 = first and 3 = second).
