Summary: Cilium and Envoy packaging was always problematic and hard to maintain because of Envoy using Bazel buildsystem and bundling lots of dependencies through it.

We tried once "unbundling" them all, but doing so manually resulted in spending weeks on that on each update.

Then we tried to automatize creation of "vendor tarballs", but this automation eventually stopped working for newer Envoy versions.

Since we are already documenting how to use rke2 with MicroOS/Kubic, and rke2 uses container images built from Dockerfiles, using docker.io registry and Github, I would rather stick to rke2's approach.
