I was hoping to spin it as an environmental concern. You change something "for reasons". If you're doing this in a popular tool/library you probably just burnt down a small forest of trees worth of energy from all of the work people will have to put in deal with it. 100s of thousands of users missed dinner with a kid or loved one because of the extra work you created. A product that would of shipped on time didn't. Things you wanted to exist didn't because 100k people were distracted dealing with your breakage.
