@galipremsagar I have a complementary PR in progress - it doesn't overlap much with this one, but let me know if you plan to expand the scope of this PR.

I was looking to expand the scope, but thanks for letting me. Let's coordinate offline.

@galipremsagar this looks good to me, but just to prevent any overzealous reviewers from reviewing prematurely before you and @bdice sort out PR scopes I've marked this as DO NOT MERGE. Feel free to ping if you need extra reviews/eyes.

[bdice]

@vyasr We chatted and we're going to merge #10663 first. This PR may have minor conflicts in one spot but should be ready for review.

[galipremsagar]

This is now ready for review

[bdice]

LGTM. Thanks Prem!

Also: nice to learn about Sphinx's nitpick_ignore.
