The way this staircase seamlessly melds into the next floor up

Oooh that's sexy. As are those windows.... oh and the floor.

No thank you! I just know I'll walk a touch too far and slip down the side, cracking my skull in the process.

Cool looking? Yes. Waste of usable space? Also yes. Has become a falling/tripping hazard? Again yes.

Looks good, doesn't work.
