This codebase is probably terrible, because it was mostly written by AI. I manually edited certain bits, but there are large sections of the codebase I literally haven't looked at.
Is this a problem? The app works well for me!
My point here is, I'd really hate to gatekeep software development to a small group of "licensed" engineers. In fact, I want the opposite: to empower more people to make software for themselves, so they can control their own computers instead of being at the whims of tech giants. (This is also why I dislike iOS so much.)
I do also take your point about safety, but I think we need to acknowledge that not all software is security critical and it doesn't need to be treated in the same way!
