Review Comment:
   It is on the `package-info` which is how we add annotations to packages 
   
https://github.com/apache/beam/blob/45bebebdafe7c8df707259ca11c5633aebdb3933/sdks/java/core/src/main/java/org/apache/beam/sdk/util/package-info.java#L24
 but also understand that people will use it anyways and/or may not be aware of 
package level annotations.
   
   We have made some breaking changes in `util` but it is rare as it is 
typically easy to maintain the existing code and just add the new use case 
under a new method.
