That's an excellent point. I suspect more mods to Dragon V2 as SpaceX
and NASA gain experience with it.

Henry Spencer over on the Arocket mailing list has already suggested
that for re-usability actuated shutoff valves be used to hermetically
close the pressurization path in place of check valves.

I suppose it will come down to how easy it will be to replace the burst
disks between flights.
