Currently the flex container is often the most scalable way to build views in perspective outside of hyper-specific ones likes P&ID. Often it is recommended for people to break the habit of thinking in coordinates, and to think "flex-first" in their development to make things responsive more "by default". Changing the default view when creating a new view would streamline things for developers who have already adopted this mindset, while also helping nudge new users migrating from Vision, to help them think about the reasoning behind Flex vs Coordinate in new development.
