Can you elaborate what does "framework runtime where concurrency and parallelism are first-class primitives" means? Because to take Flask for example - it can run the "sync code" example on your page perfectly. It even has thread-pool support, if you run it via gunicorn. And if you want to mix sync and async code, you can do this too: https://flask.palletsprojects.com/en/stable/async-await/ https://flask.palletsprojects.com/en/stable/async-await/ So what exactly is the innovation of your framework compared to that? Perhaps the easiest way to explain this would be to show some code (non-working is fine) and say: "this thing is easy in my framework, but very hard / impossible in existing ones, like Flask". I think this is what you tried to do with "what if we simply wrote" section, but you kinda failed because you can already do this anyway.
