The goal of shifting / stitching the flows on the forward path that we
choose sounds perfectly fine from the view of realizing optimized data
plane. But, we still have to show how an operator can manage the
subscriber session and enforce the policies. Without such considerations,
we cannot meaningfully evaluate the solution, IMHO
