Well it doesn’t work for anything that would need actual back pressure support ;-> (well, of course it would ‘work', but would be very inefficient and quickly overload the server).
A done callback should do.

I can’t follow you on this one. Why would I have to parse it? If I eventually detect that the content is more than I want to handle or that they payload is b0rked (e.g. invalid iCalendar data, or amount exceeding limits, says it sends a text/plain but actually uploads an avi etc), I would just want to close the stream?

That is exactly the point, if someone is sending you endless or invalid or unexpected data, you want to stop that from polluting your server and just stop.

No one is complaining, just passing on notes ;-> So your plan is to send along an updated proposal at some point?
