Well, no. That's what I meant to explain. You either need content-length
or chunked encoding. Otherwise, the client cannot know when the transfer
is finished and needs a FIN for that.

If I'm not mistaken, there's a form of chunked encoding that can do
without length, but I haven't really digged into that at all.
