Uhm... yeah, it's a bit invasive... but that happens when such improper
naming is done in the first place :-/

It's similar to when tools wrongly or ambiguously use SI prefixes,
instead of proper kB, MB, GB, etc. (for base 1000) respectively KiB,
MiB, GiB, etc. (for base 1024).
Especially just using K,M,G, is simply evil and should lead to public
punishment ;-)
I'm also not really fond of what btrfs took over from LVM,
namely kKmMgGtTpPeE,... it's ambiguous or at least unclean as well...


Best would be probably if we don't use "raid" as names at all (or just
as aliases for the actual canonical names), but rather describe what's
actually...
E.g.
classic RAID1 = mirror
btrfs RAID1   = dup2 or something similar like clone2, replica2
classic RAID0 = striped
RAID5/6       = parityN



Cheers,
Chris.
