AI Summary: After upgrading to module version 21.X, the user discovered that the `self_managed_node_group_defaults` input variable was removed. This breaking change is not documented in the `UPGRADE-21.0.md` guide, leading to confusion. The user requests that the documentation be updated to reflect this removal.

AI Summary: The GitHub issue reports a bug in `terraform-aws-eks` module versions 21.0.5 and higher, where specific EKS Addon timeouts (`addons.someAddon.timeouts`) fail to correctly override global `addons_timeouts` settings. The global defaults are unexpectedly ignored unless an empty `timeouts = {}` is explicitly set for the individual addon, leading to incorrect timeout application.
