Many have have advocate for such and it is not entirely crazy. I don't agree with it, but it is hardly wtf-worthy.

I think it is actually a kind of wtf that there are no certifications for software devs that make life and death things, life auto-pilot or pacemaker software.

There likely are in many cases. I don't know about software specifically but in other engineering professions, professional engineer licenses are often required when you sign off on drawings, etc. for regulatory boards. If you are responsible for a ship design, you absolutely need a PE.
