Hi @aayushsss1 - Thanks for opening this!

To set expectations appropriately - the linked issue is a breaking change slated for inclusion with the next major version of the AWS provider (v6.0.0). We have not yet begun work or planning for this effort, so this PR won't be reviewed by maintainers until work for v6 begins, likely later this year.
