I believe that the scope of this pattern extends beyond rollup. We have aggregates, e.g. counter_agg, that employ this technique even when called without rollup.

Also it's probably outside the scope of this PR, but I think it would be helpful for us to eventually include a treatment of why this is preferable to ordered set aggregates.

I took a first pass at a longer explanation with a bit more context around this choice.
