well, "because it's not ideal" is not the whole story - there's a WHOLE of stuff that got in the way, not the least of which was a house fire but that's whole other issue.
as for your idea of the difference between bodybuilders and powerlifters, that's not at all true.
primary focus of a bodybuilder is symmetry and form. power is the primary focus for powerlifters, even if it leaves them looking like a hulking gorilla.
the idea of powerlifters being big and bloated is old skool - the modern powerlifter knows he doesn't need to add pounds of extraneous weight to achieve the same results.
