Fair point.
'agg' seems better to me than 'aggregation' when used in a name: it's
shorter, and it's unlikely anyone would interpret it as anything other
than "aggregation".
I kind of wonder whether we need to include 'partial' in the name.
Given the context, it seems very clear that we're referring to
partial aggregation rather than final aggregation.
So I'm weighing between "apply_partial_agg_at" and "apply_agg_at".
