My thoughts as well. The trap you mention is typically a linear environment with a solid-yet-comical (or whimsical) narrative, ala Portal. That allows the featured game mechanic to be introduced at an optimal pace, effectively realizing more milage out of it. It's also the safer and more conservative route.
As a little thought experiment, I wondered how the perspective mechanic in tMoST would work in a completely different genre, and I figured it'd be pretty entertaining in say—an agent-based MMO simulator. I mean, just imagine watching a bunch of simulation agents wander about the map, trying feverishly hard to properly size objects to their liking. That seems as if it would at least be amusing. Bonus points for proper physics so they can accidentally crush each other with giant, oversized objects.
