I think I could find several use cases if I wanted to :) For example I
would often like to broadcast some model information to many downstream
operators at once. (not exactly broadcast ,maybe only to a couple of them)
Also even this does not give full flexibility. Imagine a scenario where I
have a self loop, and I want to send something to all others (except myself),
to do this I would also need to know my own channel index...
