Also unfortunately but we can't return anything but an EJSON value from
this because there's no way to insert a convert-to-EJSON step later on. And any
attempt to do so would be outside of the standard reduce function APIs and
would prevent any non-builtin reduce from participating in that protocol (cause
other language can only pass JSON around).
