[jira] [Created] (SPARK-28855) Remove outdated Experimental, Evolving annotations

Sean Owen created SPARK-28855:
---------------------------------

             Summary: Remove outdated Experimental, Evolving annotations
                 Key: SPARK-28855
                 URL: https://issues.apache.org/jira/browse/SPARK-28855
             Project: Spark
          Issue Type: Bug
          Components: ML, Spark Core, SQL, Structured Streaming
    Affects Versions: 3.0.0
            Reporter: Sean Owen
            Assignee: Sean Owen


The Experimental and Evolving annotations are both (like Unstable) used to express that a an API may change. However there are many things in the code that have been marked that way since even Spark 1.x. Per the dev@ thread, anything introduced at or before Spark 2.3.0 is pretty much 'stable' in that it would not change without a deprecation cycle.

Therefore I'd like to remove most of these annotations, leaving them for things that are obviously inherently experimental (ExperimentalMethods), or recently added and still legitimately experimental (DSv2, Barrier mode).
