I really like this initiative, I think the biggest value here isn't the multiple sessions or worktrees, but an interoperable protocol between these coding agents through a new UX. A sort of parent process orchestrator of the many agents is something I want, is there other tools that do that today? e.g. run Claude, Codex, Gemini, all together and sharing data with one another?
