Are HTTP operations really stateless? How does FieldsReader's chunked
and keep_alive fit into this picture?

I assume that you are thinking about HTTP/2 multiplexing here.

The situation is somewhat similar to unconnected UDP sockets, where you
can receive datagrams from multiple endpoints on the same socket. It is
possible to emulate connected UDP sockets (you can also make UDP socket
connected directly, but it has some unwanted consequences) with pseudo-
sockets that appear to be connected to a single endpoint even if it
communications over an unconnected UDP socket. Here is an example of
that:
