Stas is more like, "I have pushed this button in the past for this very project, and it caused my downstream users to blame me for their software breaking, and so I don't feel compelled to continue doing so." On the whole though, making a comparison to trolleys crashing or $100k being wasted is a poor analogy. So there's no uncertainty, we are talking about a project maintainer refusing to remove a warning that he thinks shouldn't have been there in the first place. It's not like there's in-fighting on the same project. It's that one independent project can't convince another independent project to make a change materially inconsequential to either.
