You're willing to say that if I update one of my packages that has a script of 30 lines, is a leaf node, and the update is to give the script an optional argument to print output to stdout instead of writing to a file that I'm incapable of building that package and then QA'ing the package from the update-testing repository? I'm specific that this is not a major problem because the number of packages that can fall into this category is small. But #3 is not a sterling example of an axiom as there are packages in the repository where small changes can be applied and tested for regressions by a single person. -Toshio
