You're abusing the notion of a straw man, which this is not. I am pointing out the consequences of Shasheene's idea as xe explicitly posited it. Xe is free to think about different sizes in turn, but needs to measure and calculate the consequences of whatever size xe then chooses. No, it would not apply the same with different sizes. Think! This is engineering, and different block sizes make different levels of trade-off. The lower the block size, for example, the fewer packages end up being the same rounded-up size and the easier it is to identify specific packages. (Hint: One hasn't thought about this properly until one has at least realized that there is a size that Debian packages are already blocked out to, by dint of their being ar archives.)
