public @interface Incubating
```
Marks the annotated Java element as incubating, potentially recursively. An incubating API is one which is still being actively developed and therefore may change at a later time; a "tech preview". The user of such an API is considered an early adopter who helps shape the final definition of the API.

Implementation Note:

Defined with RUNTIME retention so tooling can see it
