I'd guess that most people will be thinking about btrfs RAID management= in LVM=20 or MD terms, so the zero-superblock option should be available in the b= trfs=20 tool proper (as similar option is avaiable in mdadm). Adding it is trivial (look at my V1 patch) and does not introduce speci= al=20 code. What's more, wipefs demages only the first superblock (so the fs is sti= ll=20 mountable using btrfs-select-super -s 1 ), while btrfs device zero= - superblock removes all superblocks.
