I was actually thinking about doing this for the devguide and for the peps repos, using the "components" to determine what repo should be used.  I'm not sure the remote hg repo supports non-cpython repos.

What I was doing was converting the current prose in smaller FAQ-like sections, so that it's easier to navigate and it's in the same page where "committing" is explained.  Having all the "committers FAQs" here has the advantage that it's easier to search and that regular contributors can skip the whole page.  OTOH some committers might want to still look at the regular FAQs for answers to more generic Mercurial questions.
