As said above the gear, it would seem, was designed to provide shock absorption, probably the reason the guy that went into the sea broke his back as the gear wasn't able to do it's job. This would mean that to add RG to it, if the RG didn't drop and the engine stopped Cirrus owners would have large odds of damaging their backs if they deployed the parachute. Perhaps it's a secret safety feature and Cirrus are trying to throw off the competition.
