Everyone, thanks for chiming in.  Will mark this as closed/rejected.  For this reasons listed this thread, it isn't a sensible path for us (hairy at best, flat-out wrong at worst).  To the extent people ever have quadratic behavior problem, we already have explicit and clean ways to solve it with the existing API.
