It's because 'Yukikaze and Hyuuga may be relatives' is purely fans' guess. It's not backed up by any objective evidence at all. Moreover, that guess has been included in the trivia section already.

So, for the sake of 'keeping a wiki page objective where possible', it should be better not to include that piece of information which is a wild guess in nature in that box.
