I expect that would confuse more people. I'd expect a "batch mode" in relation to aggregation to be transitioning multiple input values in a single call to a transition function. I expect we'll one day have that, and likely that transition function will be called "Batch transition function" Also, I just found [1], so looks like SQL Server also calls these Partial Aggregates too. I'll stand by what I said earlier, that if people don't know what partial aggregation is that we should aim to better explain what it is. Renaming it won't magically inform people what it is and will likely just confuse all the people who already know what it is. I think you're about 10 years too late to bikeshed names for this.
