Today, podman (really https://github.com/containers/netavark/ ) still uses these compat interfaces...I'm a little surprised that there's no "can run a container" gating here on MRs.
I think we need to more formally track dependencies of these iptables interfaces before we can remove them.
(To be clear I am not sure this is the MR that caused this behavior, but it's my best guess)
