So you do just want to do it all via kind 1 events then? But what if I want to call an AI model with specific parameters, or what if I want to compute a web of trust to filter out my events, or what if I want to generate an algorithmic feed? To do any of those, I need to give more structured information as an input and it would pollute the kind 1 space.
