I don't know why. Several companies build entire frames out of any number of species: including white pine. It is important to remember the books we treat as gospel (Soban, Benson, and Chappell) were written some time ago by men still learning their craft. I have heard Tedd Benson say he regrets many things he said in his first book and I would posit that Jack might feel the same way.
My fun and my two scents: smell the fervor.
