It's the same when you are using sprockets and chain. It is in the design and implementation that makes it safe of not.
First of all, I am not a LRI, just a lowly RI and of course it would be escalated.
Second, there are always tanks available at competitions so replacing a questionable tank is not an undue hardship on the team. A box around the tank is also a safe option.
Third, the blue box on R76 says "Consider pneumatic components sacred". That is stronger language than sprockets and chain. The tank will have a torque specification on the fittings, how does a RI verify that it has never ever been violated?
Last, the push in fitting tanks do have a limited life, but the failure of the fitting results in the tube being expelled in a safe manner.

I personally think the risk of using the tank in question is too high and would not use it even for practice.
