OutputType byte solution is nearly equivalent to {x,y,z} and adds redundant
data. Implementations could erroneously (maliciously) assign the wrong
output type for the given purpose field.
We could reduce the scope of this improvement to BIP43, as suggested by
Thomas. BIP32-generic wallets may implement something else.
