I know scratches and dings weaken carbon fiber bicycle frames so bottles probably are the same.
I'd been looking for a sleeve or wrap for protection. I think a British airgun co actually sells precut heat shrink for this purpose.
I ordered 3 to 1 non adhesive 3" diameter tube. A 5' section was $50 so not cheap but enough to do five bottles.
I thought it turned out pretty nice!
So long as you always fill it yourself it is not a problem. Any Company that fills bottles needs to see the the date it was made and last hydro tested or they will not fill it.
