Can you put your proposal on GitHub under your swift-evolution fork? It’s really hard to follow the current state of the proposal and the changes over time.

The forwarder will receive forwarding implementations of the members, but again does not need to declare conformance. Forwarding is orthogonal to conformance, just as it is today when you manually write forwarding members today.
I cannot think of a time where I wanted this pseudo-conformance. The entire purpose of forwarding, that I’ve ever wanted or seen at least, is to act as a pass-through from the outer type’s conformance to a protocol to an internal specific implementor of that protocol without having to write all of the boiler-plate code to make that happen.
So I find it confusing that you say they are orthogonal.
