I have not been given a specific example of a scenario involving uutils, I have only been told about scenarios for unrelated and very different projects, and the difference between the situations is significant enough that you can't simply point to them and declare that your point has automatically been proven. In fact, I would argue that uutils is such a different case that it is implausible that such a scenario could occur and become a big problem.
And yes, people stopping complaining about work being done on a project they are not involved with in every single post discussing it would be a perfectly fine outcome for me. But if they are not going to do that, then I would also be happy with getting my questions answered because I believe that they are relevant.
