I get it's pluggable, but it's yet another hurdle to jump to get started on K8s. So maybe dont make it included, but make it much simpler to add it in and use it. They already have one that they support, it should be more plug and play with simple steps to route your app, knowing that this will be the case for most uses.

Most of the time when you 'get started on K8s', you get started by using a cluster that's setup by a provider of some sort - be it a cloud provider, a platform team in your company, or some prebundled bare metal Kubernetes distribution like K3s. In these cases, a you will most likely already be provided with, or at least recommended an Ingress Controller.

Setting up K8s clusters from scratch on bare metal (or even worse, VMs) is generally not something you should be doing, unless you really know what you're doing and have a good reason to. Think: going 'Linux from Scratch' instead of installing Ubuntu. K3s is not an alternative to K8s, it really just is a distribution for bare metal deployments. So is Rancher, OpenShift, etc.

I would argue that an ingress is not a barrier to getting started with k8s (even with kubeadm on bare metal). You don't NEED an L7 router to get started. Much more likely is you need a LoadBalancer. An ingress is only going to help route traffic that is already in your cluster.

If you deploying to almost any cloud provider they have an implementation for you. If you're on bare metal, you have to make that choice yourself.

Even if you're hosting yourself you don't technically need a load balancer, you could use host ports, or node ports and it would work for some definition of work. I have in the past set up an ingress to listen on host ports of every node and it works well, if a little janky.

I'm surprised you're complaining about this which is an easy thing to replace and not your choice of network plugin, which can result in having to reprovision the cluster or similar if you want to replace it with something different.
