All they really had to do was find a way to make the keys more easily removable. The butterfly mechanism is really nice when it works, but when a single key can stick and there is no easy way to clean / replace it so you have to replace the entire cop case which is insane.
And you are correct. Just got back from the Genius Bar, they have to replace the entire top case because the R key tends to stick or misfire. 2 week repair because they don't have the parts. Sounds like an expensive repair for a single key.
The person sitting next to me had the exact same issue (but different keys)!
