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