I do not get the focus on collaborative editing (surely niche?) while the Remote Development in VS Code (in which "remote" can mean in a docker container running on your local Docker, or a container elsewhere, or a whole-ass other computer you own, or a rented computer/instance in le cloude) seems like such a more game-changing feature, similar in some ways but probably less work.
And make that the thing you charge for. ¯\_(ಠ_ಠ)_/¯
