  The performance gap was reduced, but not closed (the filesystem layer
still has a say every time the swap is accessed).

  And it adds one more way swapped-out data could be accessed by
(possibly malicious) processes, i.e. accessing the contents of the file
(that's the reason swapon checks the file's permissions and does warn
you if they allow anybody other that the owner to read it).
