Is there a reason why there aren’t delay functions for channels, and only for flows?

Is it just that it isn’t as efficient to do so with hot streams?

It quickly becomes inefficient when you apply multiple operators to channel, so the pattern we want to enforce is that you take your input as flow, apply flow operators, then convert the result to the channel (produceIn operator) if channel is needed.
