The strength of Kubernetes (vs Mesos, OpenStack, etc.) is that you can strip it down pretty well so that you only bring the niche bits that you need - whether it's edge, or something big that needs a lot of extras. The unified API mechanisms and moving drivers out of core helped a lot there. Also, in my experience, it turns out that you can quickly find yourself needing all those extra bits if you're not Google (which implements a lot of the same features in libraries linked to programs directly and depends on the fact that they run customized everything) or Netflix (similar).
