Alas dinodino without a satisfactory theory to explain it from trough to trough, the phenomenon, no matter how well documented doesn’t really exist ~ does it!
Perhaps in YOUR internal mental view of science. In the real world, however, science often sees a phenomenon and develops a theory to explain it. I am not aware of any controversy regarding rogue waves, and in fact I have a textbook printed in the Fifties which talks about these large waves.
