Because ext23 filesystems can have block sizes other than 4K. In the old
days, when disks and files were smaller, there were some advantages sometimes
to having 2K or 1K blocks. These advantages are mostly irrelevant now, but
the lowlevel filesystem code and tools MUST be able to deal with block sizes
that are not 4K for obvious reasons.

Closer to "obsolete feature".
