Can you please rebase this PR after merging #2106? To remove the diff caused by index test splitting. Applies to other PRs as well

P.S. I've disabled auto-merge (let's not turn it on if you assign multiple reviewers)

Yup, browsing PRs in GitHub that depend on changes from other PRs that have not yet been merged is painful. It requires from the reviewer to pick the commits only from given PRs to show the actual scope of changes. Not very convenient. Since the #2106 is already merged I did rebase. But for all the consecutive PRs / branches even though they are rebased, in GitHub they show all the commits even from upstream branches :/.
