iptables 1.8.3-1~exp1 is already uploaded, currently waiting in the NEW queue. The upload is for experimental, since the build depends on a newer release of libnftnl (already in experimental), and we are at a point of the Buster freeze that I would like to make extra sure I'm allowed to push such a big diff into unstable.
Hopefully all this will be untangled in the upcoming weeks.
