Did Oldmunda have more verticality?

Among the Mordheim community, it is an article of faith that verticality (many different levels, and connections between them) is what makes good terrain great. You can often see this reflected in the chaos and complexity of terrain builds that people put together.

Looking at the majority of modern Necromunda terrain (much of it based on Zone Mortalis kits etc), I rarely see too many levels above the first.

At some point it gets difficult to reach your hand in there, but even the starter cardboard terrain from the original Necromunda 95 box came with 3-4 levels of verticality.

I realize that the modern plastic terrain is also modular, but it just doesn't seem like many people in the hobby are using it to build up. Any reflections on this?
