LGTM. Given the code cutoff for 2.16 is today and this is a dependency for other related changes, Im okay merging this in as is and addressing and issues that arise from this change in a fast follow. I dont see anything inherently wrong with this change, especially since all of its features are gated behind an advanced setting

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch-Dashboards/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch-Dashboards/backport-2.x
# Create a new branch
git switch --create backport/backport-7426-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 6a079d3eb61e9e229457eba7d26213b50ee7a7c6
# Push it to GitHub
git push --set-upstream origin backport/backport-7426-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch-Dashboards/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-7426-to-2.x.
