But that it's not really the case in the example above.

It's not the software engineer duty to know about how a given product is legal in what regulatory environment. That is something that must be hashed out upstream, well before tasking somebody to write a program.

Granted, an expert engineer with strong domain knowledge could be aware of those kind of pitfalls, and offer insights during the product development phase. But again, that should be done before committing to a schedule or making implementation decisions.
