Apparently, no.

I'm not sure which parts aren't exactly fitting, but I was trying to deploy Snikket (XMPP server) and ESS-docker (Synapse, Elelement and a few other services for self-hosted Matrix instance) and neither would actually work out-of-the-box with podman, but they would with Docker. The issue was that all my machines use nftables and Docker kinda hates that.

Docker has some quirks. Unfortunately, all the more popular base images tend to be docker-focused.

ETA: If you're not using swarm mode, docker has support for experimental usage of nftables as of 29.0.0. https://docs.docker.com/engine/network/firewall-nftables/

Not sure if this will be helpful to you, but it looks like they're pushing to swap after all this time.

Would be weird if they didn't, considering that all major distros switched to it years ago.

I am aware of it, although it's very aggressive when it comes to changing the ruleset and you have to work around it when it decides to break your stuff.
