If we want to get pettifoggingly punctilious, I'd define the Canon and Nikon framelines as "reflective" rather than "etched." The Nikon S2, for example, has a simple etched line (non-parallax-compensating) that shows up as black; the reflected framelines in the Canons involve two reflecting surfaces and show up as white. It's a significant user distinction because the reflective framelines are easier to see but involve a more complex optical system (which means more likely to need cleaning after donkey's years.)
Als... Do the S3M's lines have parallax compensation? I didn't think they did.
Now, getting back to the original list, which -- since the focus is on the "most advanced" form of rangefinder optics -- I would argue should be restricted to interchangeable-lens cameras with
projected parallax-compensating framelines, let's not forget:
-- Red Flag 20 [speaking of rare!]
-- Kiev 5
-- Yasuhara T981? (I know it had a projected frameline, but not whether it's parallax-compensated.)
-- Epson R-D 1
To split hairs further, we might argue that the "most advanced" viewfinders incorporate not only multiple framelines, but multiple
selectable framelines, i.e., use a moving mask over the frameline optics so you don't have to look at all of the framelines at once. That limitation would bump out the Kiev (since even the later models with the 85mm frameline show both 50 and 85 all the time) and the Yasuhara (which only has a 50mm frameline.)
