I'd say vertical scale should be universal and apply to all z coordinates.

To me the scale is a viewport dependent setting, which is highly
dependent on the map extent and angle to get a "good" scale. So I
think it should be that tweaking just that single setting should
universally change the vertical exaggeration, with no extra data work
required.
