Could you give an example? Most of the arguments in the post seemed to be focused on long-term maintenance. It does put a lot of faith in the upstream allowing contributions and making good decisions, especially when viewed through the lens of Ruby/Rails a belief that upstream continues to exist. To me though some of the arguments like submitting fixes is actually encouraging the reader to fork and make their own changes as opposed to using dynamic modification to behavior.
