There is a set of tools compatible with nftables: http://git.netfilter.org/iptables/ which could be a drop-in replacement.

Motivation for this change
It took a while for me to figure out that Docker uses iptables internally and that I had to disable it manually for nftables to work.
To try to mitigate the problem of "tribal knowledge" I added a heads-up in the description of the
