Good point about damping a transmission line. In fact undamped transmission lines existed before transmission lines. They were called labyrinths. And when damping(long hair wool initially) was added to a labyrinth in the early 1960s it was called a transmission line.
At first the idea of a line sounds simple but there are problems with details. Folding lines causes resonances at the folds in classic designs. And in fact even a straight line also has resonances. This is why lines are often reduced in area as the line lengthens; it reduces the strength of the resonances. Adding damping makes the resonances less and by the way also increases the acoustic length of the line by reducing the speed of the wave lengths in the line.
