For users (such as algif) it's much more convenient to have a size rather than a flag because that's what they need to determine the minimum size for partial updates. For implementors you don't need to specify the chunksize at all unless you're a stream cipher (or some other case in future where the minimum partial update size is not equal to your block size).
