Without a somewhat centralized codebase, development will be an absolute nightmare. Old versions floating about with bugs or so old there has been breaking changes in the API, and did you make your additions to the latest version...no wait, 4 people made different additions around the same time, but each released their own versions, and they were not based on the same version either. With no single place to report and collect fixes and development it'll be a fragmented pile of crap real fast.
