Yes, by .rst docs I mean the final HTML output, not the .rst files

increasing popularity of IPython (even outside of the scientific
community), more and more people are becoming used to using docstrings
as a first means of finding out about a function's behaviour.
That's a good point. I would still posit that HTML documentation gets by
far the most use, but docstrings are definitely important too. One more
point in favor of either:
1. Maintaining both, as tiresome as it is (we try to do this, not always
successfully, for all stdlib modules).
