Came here to say this, yeah.

UDB supports a lot of the fancy new features from ports, like the Eternity Engine portals, or the 3d floors GZDoom gives you.

Even if someone wanted to map for good old vanilla limits, the newer nodebuilders can both minimize things like slime trails and add effects like infinite horizons (this one is fun, it rotates the wall rendering by 180 degrees and since it's a single-sided wall, it just keeps rendering the same floor and ceiling texture forever).
