That's true.

I just wanted to solely rely on the 200 code when the request was
*completely* fulfilled and have a way to signal the client to also look at
the body when it was *partially fulfilled*. But having a content length of 0
in the first case would basically do the same, right?

Hmm... No. You are right, indeed it has no advantage of creating a specific
response code for that as it won't tell you more about the result than a
200.

Thank you very much for the feedback
