It won't have a lot of oxygen though. I would accept the "risk" to leave the Kraft in place based on likelihood of low ignition, and based on very reasonable likelihood if it did ignite, the hazard would be low. Settling of the blown insulation only reduce oxygen availability to the Kraft paper. Wind effects are unfavorable factor, but not enough so to change my mind. Might offer a compromise and somehow secure the Kraft paper better in any areas that may access this space.
