What is the future of elaslasticsearch extension (OpenSearch)

With the M2.4.4 moving to opensearch by default, what is the future of the elasticsearch module? 

I would like to purchase this extension but I need clarifications on the road map and if support will still be provided by elasticsuite for the core of elasticsearch. Are we required to subscribe to elasticsuite for this support?
