Closing index and memory missing warning?

Continuing the discussion from Does close index free up disk or memory:

Maybe this warning about losing data ("To reduce the risk of data loss..." Open / Close Index API | Elasticsearch Guide [6.8] | Elastic) from 6.8 documentation should be added to 7/8 documentation. It seems to be missing: Close index API | Elasticsearch Guide [7.17] | Elastic

Or, is there a reason why it is missing? Has something changed making this warning no longer relevant?

In newer versions closed indices are tracked by the cluster and if a node holding a shard copy was to go down the cluster will recover it to another node. This was not the case before version 7, which is why the warning was in place.
