Document common error of replacing the json object

Prior to having query params and aggregation supported, this wasn't much
of an issue, but now that we have these features, we need to code
against doing multiple things in parallel.  We have had cases in the
past prior to these new features, but these were generally localized to
a single handler, so the fixes tended to go under the radar.

This commit documents this common pitfall, and propose a solution.  The
commit below has already done most of the work to make the codebase
consistent in this regard.  Documenting this will hopefully ensure that
regressions don't happen again, or if they do, we have documentation
that we can point to.
