So you're arguing something else entirely, gotcha. > The program is being made less brittle because it is tested in different environments and the practical max amount of dependencies are lower than shipping a custom distro for your program. If we're talking about web (which is my assumption since images don't make a lot of sense otherwise) there is exactly 0 benefits to testing apps in different environments since they're only going to be deployed in one, right? And either way if that changes you can specifically test for any other envs you want to run your app in, and not let your developers take that pain onto them by fighting deps/configurations along the way. Either way it's painfully obvious why one is better than the other.
