- DRA device taints: `DeviceTaintRule` status provides information about the rule, including whether Pods still need to be evicted (`EvictionInProgress` condition). The newly added `None` effect can be used to preview what a `DeviceTaintRule` would do if it used the `NoExecute` effect and to taint devices (`device health`)...

- **Exception wrapping** - Checked exceptions are consistently wrapped in runtime exceptions (e.g., `ClassNotFoundException` → `ClassNotFoundRuntimeException`)
- **Bean introspection** - The comprehensive `BeanDesc` system provides metadata about JavaBeans, accessed through `BeanDescFactory.getBeanDesc(Class)`
- **Type safety** - Extensive use of generics and null-safe operations throughout the API
