I don't envy the decision makers.

NetFilter has been around ~20 years, and nft (NetFilter Tables) finally
unified all the various *tables about 5 years after that.

But it's only been about 5 years since distros finally adopted it, although
I'll give some distros credit for abstracting their host firewall tools a
decade ago so the transition users much more easily.

But not even agrees on those tools or the transition for that matter. And
some vendors are just so way, way behind, using static, inflexible scripts
that don't work well with libvirt, containers, etc...

We've seen this with other solutions too, like Docker taking forever to add
kernel control groups (cgroups) v2, among other facilities, like more
secure, non-root/insecure socket, facilities, which finally pushed some
vendors to introduce alternatives (e.g., Red Hat with podman, much like
firewalld... dynamic, secure, runtime solutions, that work alongside other
facilities, and can insert/reload rules upon dynamic infrastructure
changes).

I mean, let's face it, many Kube et al. solutions aren't very dynamic and
don't always work with various facilities, and it's very frustrating in
financial and other, regulated, high compliance environments, which
customers then push their 'Enterprise' vendors to address.

So, where and when nft comes in, I don:t know.
