Part of configuration which can be customized for each type/group of nodes(etcd/controller/worker/) by its nature.

Please beware that it is described as just "by its nature". Whether it can actually be customized or not depends on you use node pools or not. If you've chosen to create a single cluster including all the worker, controller, etcd nodes within a single cfn stack, you can't customize per group of nodes. If you've chosen to create e.g. a separate node pool for each type of worker nodes, you can customize per node pool.

Though it is highly configurable, it's basically users' responsibility to provide `correct` values if they're going beyond the defaults.
