It's my impression that there are lots of platforms that ask very little of their environment, and therefore don't benefit much from Docker, and therefore can be developed with minimal friction in a local environment without using it. Node, Java, often Python, even Rust because of its static dependencies, etc often fall into this category. And of course front-ends, especially. In practice you'll still use Docker to deploy because it's a nearly-unavoidable deployment protocol at this point. But I see very little reason to have it house your in-progress code in these cases.
