I would argue that, even if they fix all inside-the-park views of TRON, its show building is still technically on stage because it's so prominent when viewed from the Contemporary, and you have to consider that one big aspect of the allure of the Seven Seas Lagoon resorts is the ability to look out your window at the castle. You pay more for a room that looks toward the park, and a big box to the right kind of spoils that.
I can see where you're coming from on backstage views mostly only visible from transportation, but Ratatouille is really close to being a bit of extra magic as you zip out of EPCOT. They could seriously fix it with some landscaping, a gate, and a few yards of facade to wrap around the edge of the building to meet with the rooftop access stairwell. If they wanted to get fancy, they could continue it past that or maybe even create a simple parallax art installation on the rest of the show building with "goodbye" in various languages when leaving and "hello" when arriving, but even that wouldn't be necessary. Just resolving the edge and tidying things up would work wonders.
