I don't think haki is so special power(except Conqueror Kings) most of the strong pirates in One Piece has it. I think every SH has is but they don't know. I think Luffy will teach the basics of it. Somewhere in the New World they are going to clash with a crew or group that every member of it has DFs so they have to use their Haki's to beat them.
