Yep, Love it or leave it. :-)

No one has demonstrated that using equivalent impedances etc is not a
valid analysis of the steady state behaviour.

Negative assertions are usually impossible to prove.
The onus of proof is upon the ones who assert that
reflected waves cease to exist during steady-state.
The distributed network reflection model has yielded
valid results for a century or so. Ramo and Whinnery
go so far as to talk about the forward power flow
vector and the reflected power flow vector. People
trying to discredit that model just haven't accomplished
their goal.
