I appreciate the decisions for the lambda iterator, but I think this is something that should have a much higher priority and make it into the coming c# version. this feature is really important for http2 streaming with minimal apis and espacially these days, where we'd like to add LLM responses. I know that I could just use a handler instead of a lambda, and that what I am doing right now, but honestly I got so used to the minimal api with lambdas, that it feels arkward to go back to handlers or controllers.

I really hope to get this feature in the coming c# version.

There is next to 0% chance that it will be in C# 14. Our hands are already full with our existing plans for C# 14.
