Probably the scale and usability of things. It's different if you're controlling 100 LEDs vs 5,000.

I use a few hundred at most and in those cases I just feed power at several points in the chain to reduce resistive losses in the wiring. But yeah I'm kinda interested what kind of huge installations would need that and how they work.
