- When asking the user for an input, does it support multi turn user conversation? Yes, it supports both multi-turn conversations from the llm and you can programmatically ask the user things too -> https://www.banyango.com/margarita/latest/user_input/

- Who is this made for? I think this is crux of my issues so far here. I have been targeting developers who maybe don't see as much value in this as you mentioned.

That said I think that there is a decent cost to developers for maintaining code each time you want more determinism, or don't want to spend tokens on repeatable steps. My hope was that having a lower cost solution closer to markdown would be a nice middle ground.
