I agree. What about decentralization in development? Gavin recently said that he wants to "get to the point where there will be multiple robust implementations of the core protocol."
When I look at this image (

With this level of centralization, it may be possible in the future for a group of coders to prevent important changes from being made in a timely fashion (e.g., should their interests no longer align with those of the larger Bitcoin community).
It is my opinion, then, that we should support multiple implementations of the Bitcoin protocol, working to reduce the network's dependency on Core.
