I think it was Mike Mearls who lamented about the bonus action.
Mike Mearls said that if he had it to do over again, he would have just made the bonus actions part of your action instead, presumably like the Extra Attack feature. When he thought about it some more, as I recall, conceded that the bonus action structure served as a useful limitation. It's been a while since I saw that Happy Fun Hour, so I might be misremembering certain details. He had mentioned it initially, I think, in a tweet, but I'm not sure.
