Possibly a different feature request, but wanted to raise the idea and seems very linked. Langgraph has a way of doing dynamic fan out, via a Send API. It enables interesting and efficient flows, specifically when the number of parallel edges in the graph is not know ahead of runtime.

Perhaps something similar is required here?
Interested in the maintainers' thoughts.
