This is not a sufficient check: there are cases where these headers are not present, but we are nonetheless confident of the length of the response. Specifically:
- Responses to a HEAD request
- Responses with a 204 or 304 status code

The HTTPResponseDecoder will always emit a response .end after having received a response head, if the request had a HEAD or CONNECT method or the response status is 204 or 304.
For this reason, we can expect that we will only be in the streaming state, if we have a "content-length" or "transfer-encoding" header or if the response is EOF terminated. I'm well aware that this is very implicit. If we want to have explicit checks here, I will need to come up with a way to preserve the request method a little longer.

Hmm, can we get this logic into a comment then? The correctness of this code is not apparent merely from reading it.

This comment seems to be out of step with the code: it implies that we can ignore the error, but then has logic that sometimes doesn't ignore the error.
