I'm not an F2FS expert by any means, but I think that's correct.
from Neil Brown's LWN writeup a while ago:

I'd encourage those advocating for enabling this to put it through its paces,
and see where it's at, rather than keying off phoronix & ubuntu.
In particular, getting [x]fstests up & running on f2fs shouldn't be too hard,
and it would be good to see if it uncovers any problems.
There was a patch to enable it on the list:
but it's not merged... I'll ask Dave about that.
Fedora succeeds when committed people share their time & effort .. can you
give f2fs a go w/ [x]fstests and report back? Scratch that itch. ;)
I can give you a hand running xfstests if you need it.
