- do not need to restrict prefix exclusions that do not have `/` as suffix, relax this requirement as spark may have staging folders with other autogenerated characters , so we are better off doing full prefix March and skip. - multiple delete objects was incorrectly creating a null delete marker on a versioned bucket instead of creating a proper versioned delete marker. - do not suspend paths on the excluded prefixes during delete operations to avoid creating `null` delete markers, honor suspension of versioning only at bucket level for delete markers.
