Thanks for the comments.
Let's take the following example:
1) 2 RAID1 + 1 spare
(A + B) + C
2) 3 RAID1
(A + B + C)
At least in normal operation case, case 1) makes device C useless, and
Yes.
For case 2), we can just relocate and recover the bad chunks in B.
It it should only

something that's very useful and helps BTRFS to compete with many
