### Question

I am using serverless framework with localstack and I am unable to define an `AWS::OpenSearchService::Domain` resource. I guess I'll have to use `AWS::Elasticsearch::Domain` instead but it is deprecated. Are there any plans to add `AWS::OpenSearchService::Domain` resource soon? 

### Anything else?
