Versions: Opensearch 3.4
Describe the issue: Breaking changes - OpenSearch Documentation Explains the Access to system indexes through the REST API is no longer provided pointing to PR Block access to system indices from REST APIs · Issue #7936 · opensearch-project/OpenSearch · GitHub which is still Open.
Additonally, In this doc System indexes - OpenSearch Documentation it says “ Even with a user account that has read permissions for all indexes, you can’t directly access the data in this system index. “
Can clarity be provided on exactly what operations are now restricted to what user(s) on system Indices ?
