What lack of sparse file support?

$ dd if=/dev/zero of=aa bs=512 count=1 seek=1024
1+0 records in
1+0 records out
$ d aa
-rw-rw-r--    1 puw      puw        524800 Jun 21 03:26 aa
$ du -h aa
8.0k    aa

There is no flag because it is always supported (given filesystem
backing, and all unix-like filesystems support it). Just truncate it to
the size you want it to be.
