I disagree, I think there'll eventually be huge demand for these kinds of frameworks and wrappers compared to "plain old Kubernetes", much like how a high percentage of developers are hungry for something to use on top of plain JavaScript. I could even see the demand eventually surpassing demand for Kubernetes itself. Kubernetes offers a ton of modern advantages - even for pretty small projects - at the cost of a huge amount of complexity and required learning.

If you can get the advantages plus something simpler than Kubernetes or homebrewed solutions with Docker, then I suspect a gigantic market will form. I think it's just a question of if it'll end up being this particular implementation, or an alternative one, or a full-on standalone competitor to Kubernetes designed for simplicity. We're still in the very early days.
