I work on a commonly used piece of software, I also make jokes to my colleagues about the software that I work on, many of us do. If I had infinite time and infinite money and infinite power, and there was no downstream risk to any of my updates, then I'd fix every single thing that I don't like about the software... things that I know other engineers don't like about it. But insofar as I am not god (... yet?), all I have is my good humor and congeniality.
