It shoots for blocks most able to handle the entire data chunk instead
of shooting for the first available chunk no matter what like every
Microsoft filesystem does. You'd think MS would bring their

No. Defragmenting filesystems that don't suffer from it appreciably
to begin with is a great way to needlessly endanger data integrity
with no benefit.
