Software engineering is such a broad field, and spans work from making a web app to building mission-critical software for a nuclear power plant. "Professional ethics" are demanded for all the professions you described because there is no "web dev" version of an accountant or doctor - their work, when done improperly, can damage human lives. The thing is, software engineering in regulated fields already is regulated. A degree is required to work on software for many medical device companies, regulations are in place to ensure code is written safely. Could all of this be improved? Sure.
