People have mentioned here that a Heroku-like layer would be incompatible with k8s. Based on the description of k8s as a distributed OS, I don't understand how to reconcile these things.

I'd want to deploy a k8s infrastructure, but have an easy experience on top for developers that might not maximize k8s use initially, but allow devs to move down a layer eventually. The whole time the ops folks would be running k8s and limited layer above that'd keep devs in a particular lane.

Isn't this feasible?
