You won't hear me complain about this one. In fact I hardly ever complain about a building not being taller.
What occurs in some cities (w/o view cones) is an area is just zoned to a certain height, it manages to avoid a tabletop effect due to the natural rising and falling of the terrain. It creates a fairer playing field with a more natural appearing skyline. The properties located on top of hills become more valuable then those at the bottom of the hill.
Wonder what d/t would look like with a 150m height limit across the core following the terrain.
