I disagree entirely, tbh, the only advantage of layering I see is precisely in the runtime: it makes the layers that change most very slim and easily deployable.
Repeatability is great, but who doesn't have that already? Are people really building new OS images for every deploy? I don't believe that for a second, and I can't think of many tools off the top of my head that don't have that baked in right from the start. That's the whole point of package management.
