This is great feedback Nathaniel. :) 

Luckily, no nasty hacks involved. I've updated the pypa-theme to support both global and local toc so that projects can pick whichever is most appropriate for them. See the commit here https://github.com/pypa/python-packaging-user-guide/pull/305/commits/12afb52f76fc33ad43438ec6b58c7333a6186b07 and I've restaged the preview here http://temp.theadora.io/pypug-pydoctheme/current.html#installation-tool-recommendations (caching might make it take a second, but visit any other page and you should see it).

Let me know if that addresses your concerns and if you have any more!

Personally, I always use the RTD theme for my projects because it has
a subtle but major advantage over every other Sphinx theme: it always
provides an overview of the entire manual in the sidebar, which makes
navigation much easier. With other themes I always feel like I'm lost.

Compare the sidebar here:
    https://packaging.python.org/current/
Versus here:
    http://temp.theadora.io/pypug-pydoctheme/current.html

I don't care either way about the RTD styling, pydoctheme looks nice
too, but IMO this specific feature is a pretty major usability win for
most projects. I believe it involves some disgusting hacks inside the
RTD theme code.
