Is there any objective reality when it comes to reflections? How do we
really know?

Use a TDR. Observe TV ghosting. The reflection model is perfectly
valid and consistent and the outcomes using the reflection model
are the same as any other valid consistent model. An S-parameter
analysis uses reflection/transmission coefficients, i.e. the wave
reflection model. If an S-parameter analysis is not valid, a whole
@#$%-load of electronics should not be functioning as they do.

I'm not entirely certain, but I believe the H-parameter analysis,
the Y-parameter analysis, and the Z-parameter analysis all use
the reflection model and are valid for impedance discontinuities
in transmission lines.
