I wanted the "New features / API additions" section to stand on its own. Once thing that might be redundant now is the
following sentence in the "Contributing code and documentation changes" section:

"Feature requests, in particular, must be discussed ahead of time and will require significant effort on your part."

I think that could be removed or incorporated in "New features / API additions".
