It would be nice if connection errors could be reported to the caller by awaiting on the connection, e.g:

let connection = Connection::session().await?;

if let Err(err) = connection.await {
  error!("Something bad happened: {err}");
}

I wonder if there is anything other than an error this Future impl can return. If it can only resolve to an error, that's what the output should be and not a Result.

It should probably return a Result<(), ...> in case the connection were to close gracefully (see #309).

hmm.. yeah if we go for #309, then definitely.
