One of the principles of superposition is that you can apply

One of the assumptions in your model is that the source
impedance remains constant with varying degrees of
incident reflected energy. That assumption is false for
an IC-706.

Which is, of course, why all my examples explicitly state the
construction of the generator to be one that is guaranteed
linear. But if the behaviour for this kind of simple case
can not be understood, there is no hope for understanding
a real transmitter. The argument "since I can not understand
a real transmitter, there is no value in understanding a
linear generator" seems weak.

The problems presented in the examples are solvable and
have been solved in public on this group.

:-) Then publish the results in QEX and settle it once
and for all. :-) I predict that QEX will refuse to publish
your ideas.

I would hope so. The ideas are quite basic, not mine, and can
be found in any standard text book on transmission lines and
circuit analysis. No need to publish in QEX. Or perhaps I
misunderstand QEX's audience and it is appropriate for them.
But then I suspect that more capable writers than myself would
be the appropriate authors.

Have you considered putting optics aside for a moment (after
all, we are trying to understand circuits, especially in the
transmitter), and cracking open any textbook that deals directly
with the subjects at hand?
