Accidents cannot be legislated against.
Look at Sportsmatch, a well regarded manufacturer who's engineering is exemplary. They received a bad batch of tubing causing iirc Tom Walton's GC2's cylinder to fail explosively. They then recalled all rifles of that batch to have cylinders ultrasonically tested. Now not everyone made it back at first so you then had a potential ticking bomb in every untested rifle. Just because a cylinder is non standard does not automatically mean it will fail, but by the same rational just because a cylinder IS standard does not mean it will be fail safe.
