I see some merit to that idea. After storing a bottle in such a way,
you would know immediately whether the bottle leaked or not when you
retrieved it. If you found that the storage bag had ruptured, you
would know to take appropriate steps to vent the storage locker. If
the bag was still sealed, you would know that the cannister didn't
leak.

I store three of those throw away cannisters in a piece of PVC pipe
secured to my Edson steering pedestal. The white pipe matches the
color of the steering pedestal, so it blends well and the material is
cheap and easy to work with. I have a small hold drilled into the
bottom threaded cap, so if a cannister leaks, it has somewhere to go,
into the cockpit which is open to the weather.
