Yes, that was considered. I do not have anything against it myself. The idea of adding the get*Blocks() methods was however partly to avoid selecting a new carrier type for the size-in-bytes values by returning the respective block counts and letting the caller make the decision of where to store the product num<Type>Blocks * blockSize.

Thanks,
