You want deformation and some bending so that less energy is absorbed by your body

Yes, deformation and bending of the body panels and crush zones is desired to absorb energy, but the roll cage is the drivers last barrier of protection and should remain intact and not intrude into the drivers compartment.
Of course, there is the perfect world where roll cages never bend and there is the real world where weight, materials, complexity, build quality, and cost have to taken into account; but the point remains the same - if the roll cage bends inward, the drivers safety is compromised.
