That's a good suggestion, thanks.

But we *do* round down the file system to whole blocks. In your
example, the final file system size is 450918 --- and the last 3584
bytes are not used by the file system. Remember, the file system size
is not necessarly the same as the partition size.
(And in some cases, the due to the minimum size needed for the block
group's inode table, sometimes the file system size can be
substantially smaller --- tens of kilobytes --- smaller than the
partition size.)
