In the .NET stack, is it more reasonable to handle Agents using a publish-subscribe pattern?

For example:
var task = agent.CreateTaskAsync("What files are in the root directory?"); using task.OnReasoning((data)=>{}); using task.OnReasoningChunk((data)=>{}); using task.OnContent((data)=>{}); using task.OnContentChunk((data)=>{}); using task.OnToolCallRequest((data)=>{}); using task.OnToolCallResponse((data)=>{}); using task.OnUsageUpdated((data)=>{}); await task.WaitForEndAsync();

Because every Agent is compatible with this pattern, including some CLIs,

and for interactive tasks, long-lived connections are more suitable.

(Hope you understand my meaning; my English is not very good.)
