The reviewers generally agree that the design choices of this framework for AutoML are judicious and hit a "sweet spot". This combination of language/tooling design is of great value to expose to large swathes of the NeurIPS community. The rebuttal persuasively addresses the reviewers' concerns about the evaluation and utility of this proposal, and the response to R4 is also reassuring. We look forward to the authors' final version of the paper, incorporating the proposed improvements.
