Neither, it's just the way things are.  In practice this sort of thing
isn't a real problem for most systems, and fixing it can be a real
pain to get right, so historically most Unix filesystems have not
bothered to try to compact/compress directories.  ext2/3 is no

One could easily argue that this would be a nice feature to add, and
perhaps some day we might add it.  But it's pretty low on the priority
