How poorly you understand NAT.

As I wrote in my draft:

    Depending on how port numbers are shared, there are static and
    dynamic E2ENAT or combinations of them. With static E2ENAT, an end
    host is assigned port numbers statically, which is necessary for a
    server with a stable IP address and a port number.

static E2ENAT is not, with your questionable terminology, stateful.

It is even possible to construct legacy NAT which dynamically,
thus statefully, assign ports only from some static range,
which does not need state maintenance, for each private IP
