This is why I do not understand people being called software engineers when they're anything but. As you said engineer is more about ethics and liability. I am designing and developing software for more than 40 years but I would never call myself an engineer. Nor would I ever want to become one.

When it comes to the issues of safety the proper outcome should be organized by a processes, verification and other things that would not let that piece of code get into production. Putting this kind of load on software developer I think is utterly demented idea.

For engineers the foremost value is safeguarding human life and the second might be protecting the environment. If anyone is developing software that can cause loss of life or damage the environment then I think the engineering ethics and processes you mentioned are a necessary load. Of course then the output of the Programmer is reduced, but that is the tradeoff to make for the type of code flying airplanes or driving cars

The processes and other things do not have to be set by programmer. It is insane to have programmers do all those things. Their task is to design develop software given constraints. Safety is a constraint that can be specced separately. And testing should be done by the independent team
