Maybe we should get alignment we want negative alignment first before adding good first issue, I would rather us not have someone pick it up and then it get rejected.

That makes sense.

@soloestoy / @zuiderkwast were already proposing on how to implement it. I guess they are ok with it. @madolson Could you also add your thoughts for the above issue?

@valkey-io/core-team Please add your thoughts. Thanks
