nftables: Request for comments - packet flow diagram

Hello,

I recently switch from iptables to nftables (I have a very simple/personal firewall).

When I built my iptables firewall I refereed to the packet flow diagram (by Jan Engelhardt) on iptables Wikipedia web page :
https://en.wikipedia.org/wiki/Iptables#/media/File:Netfilter-packet-flow.svg

Using this diagram for nftables firewall is hard as some concept changed.

I did some tests and draw my own diagram (using yed editor) covering all netdev, ip, ip6, inet, bridge and arp tables :

Direct URL and yed sources :
* https://pelican.craoc.fr/images/packet_flow.svg
* https://pelican.craoc.fr/images/packet_flow.graphml

Can you please verify it ? Feedback would be much appreciated :) I am not a network expert but the subject interest me and I would like to know if I misunderstand something.

I put this diagram on CC-BY-SA license so feel free to use/modify it if you like.

Note: I draw an arp-forward-filter chain in the diagram because I can create one, but I can't actually saw any packet going through it. I think it's a bug, so I draw it anyway. More informations :
