Repressurisation hardware has to exist anyway to have restartability (it takes 15 minutes to switch to high pressure feed, 15 seconds to low pressure feed). Do you know which component has inhibition affected? SW only? Blown fuse? Something different? Certainly not a jettisoned part, because this vehicle is planned to be reused after minor refurbishment.

PS re repressurisation failures: If it becomes absolutely necessary, a procedure could well be devised to operate the larger thrusters at a lower flow rate, albeit with a diminished efficiency and thrust.
