One benefit is that we need not anything in the initrd for hibernation to work.
Another one is that we can get superior performance, for obvious reasons
(less copying of data, faster I/O). Yet another is simpler configuration and
no need to maintain a separate set of user space tools. I probably could
find more.

That's correct, we can. But since we have LZO in the kernel now, we can use
it for compression just as well, can't we?
