Maybe this is rich coming from a Kubernetes person, but sounds like the tide is turning against this viewpoint.

Running Kubernetes itself is definitely hard to master, but you can take a <10 hour online course and be able to "helm install" your application.

Kubernetes can be the new PaaS (if you have someone else running the control plane and maybe a monitoring stack). But there's not a PaaS on the planet where you can just skip the step where you learn about it. Even Heroku users eventually have to learn about how connection handling and limiting works, and the specific Heroku commands to upgrade your database.
