It's not about being perfect, it's about being fault tolerant, just like regular engineering. I think especially for safety-critical situations (cough Boeing cough) there needs to be stringent, formal standards for quality, review, and training. It should not be possible to cheap out or ship a pile of duct-taped garbage in some situations, and that requires external review by subject matter experts. (Not necessarily government bodies, especially with the regulatory capture and brain drain going on right now.)
I think kabdib's point is that the incentives of certification authorities aren't aligned with the purported goal of the certification process. We already have all sorts of certifications (in specific technologies, "agile" practices, etc.) but I don't think most engineers see those certifications as providing any value.
The only thing I'm aware of that seems to actually work is to hold engineers accountable for results and give them the autonomy to set their own process. I would argue that even very rigorous methodologies like NASA's Systems Engineering[0] process match that description.
I am a "Software Engineer". I hold a Professional Engineer designation by APEGS, my schooling was for Software Engineering. I advocate for regulation in the industry but also don't think it needs to be sweeping and catch-all.
My job has me working within Industrial Control environments. Programming mistakes can kill people or damage equipment worth millions. When I receive a software package from someone I want to have some trust in a system that this person wasn't hired off the street for lowest wage. My employer has a good reputation in our industry and is asked to come clean up messes from programmers overseas who provide a bad system and walk away from it.
If your job doesn't have you playing with lives of people or holding the wellbeing of a company in your hands then regulation shouldn't be as stringent. But to say that every project of that magnitude has an Engineer overseeing and holding responsibility over it isn't overreaching imo.
