as maybe you already know, nftables has been merged into linux,
scheduled for release with kernel 3.13 .
There is a how-to  to test it.
nftables includes a compatibility layer, that allows a painless
migration from iptables to nftables.
nftables also features an API, called libnftables . This API adds
some interesting features to build other apps in top of it.
This software is a major upgrade in the Linux world, and I think that
when the times arrives, Debian should adapt to nftables.
I haven't heard any word in Debian about nftables, so I just wanted to
comment it here, I case you missed something.
