It's possible that the change to burst discs will not affect the feasibility of propulsive landings, depending on how the system is pressurized and used. During a propulsive landing, the Dragon capsule would test the SuperDracos while still at a reasonably high altitude; this way, in the event of a failed SuperDraco, the parachute backup can be used. (The landing burn for Crew Dragon would start only a few seconds before landing, far too late to deploy the parachutes if the engines don't perform properly.) That said, this is old information, and many things could have changed since then.
