Redis CONFIG SET requirepass "" leaves auth enabled, sets password to empty

Starting from here I believe, after you've enabled AUTH and then ran CONFIG SET requirepass "", you'll get a redis instance that requires an empty password authentication. I've noticed that by seeing our Haskell's driver test cases becoming broken.

If this is a bug – I'd love to see this logic being rolled back. If it's a feature – I'd love to see a way to remove auth from redis. Thank you!

@k-bx thanks for reporting. seems like an issue introduced by ACL (Redis 6.0). should be solved by #7899
