I expressed myself unclearly. The gas cerified person gets repercussions because someone found leaks in the pipe fittings this certified person made. The leak is a smoking gun. OTOH The software dev, certified or not, will not get repercussions because of their racey constructs, since it is much harder to point out they did not follow some certified procedure other than some (non airtight) tests and reviews before release. There's no smoking gun pointing to uncertified way-of-work. There's only this one in a million happenstance of a race condition making the system fail. That's where the common sense comes in, only that will prevent/solve possible race condition. There simply is no certified way about it like in pipe fitting.
