I would have to agree. Skulling for support with your body to the ear
in the water is great for impressing girls. It also defines where you
can put the boat on that plane. ( everywhere ) . Practically though, it
has no real purpose. It does make side surfing with a high brace seem
easy.
I have some wild roll stories but a good roll is what makes a confident
brace possible in my mind.
There is an old guy here that can roll a canoe. It is a cool but
useless trick. It comes up full of water.
