Module status and differences from other modules

Hi Centarro!

This module page/description covers an amazing set of Elastic Enterprise Search functionality. I'm curious about the module's release status since there is no code yet and comparison to other modules that provide Elastic-related functionality such as:

1. https://www.drupal.org/project/elastic_enterprise_search →
2. https://www.drupal.org/project/elasticsearch_connector →
3. https://www.drupal.org/project/elasticsearch_search_api →
4. https://www.drupal.org/project/elastic_search →
5. others?

Thanks!
