> Our MIMA binary compatibility checks currently ignore APIs which are marked as {{@Experimental}} or {{@DeveloperApi}}, but I don't think this makes sense. Even if those annotations _reserve_ the right to break binary compatibility, we should still avoid compatibility breaks whenever possible and should be informed explicitly when compatibility breaks.
> As a result, we should update GenerateMIMAIgnore to stop ignoring classes and methods which have those annotations. To remove the ignores, remove the checks from https://github.com/apache/spark/blob/643649dcbfabc5d6952c2ecfb98286324c887665/tools/src/main/scala/org/apache/spark/tools/GenerateMIMAIgnore.scala#L43
> After removing the ignores, update {{project/MimaExcludes.scala}} to add exclusions for binary compatibility breaks introduced in 2.0.
