> Currently, a view with no reduce function defined disallows having a `reduce` parameter
in the HTTP query.
> It would slightly simplify client code to always query views with reduce=false except
when a reduction is actually desired. That way, views which have useful map-only and map-reduce
output can be queried with the same reduce=false parameter. Currently, if one wants only the
map results, one must know whether that view is map-only (reduce parameter should be omitted)
or map-reduce (reduce parameter should be set to "false").
