If this does indeed compromise reusability they'll probably come up

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.
Doesn't matter because NASA wants only new Dragon 2 capsules for crew.
After their crew flight, they will be refurbished for commercial cargo.
Part of that refurbishment is to remove the abort system to allow for
more cargo up-mass and down-mass.
