Yep, that spooks me too... but Uni will have none of it unlike Disney. They know what side their bread is buttered on. And SM is the best example of that. Impossible effects every 3 minutes of every day for 10 years. Disney has a "let half the attraction not work, it is still ok" attitude on all of their major attractions. Uni has a different approach... "let the apparent infrastructure fall apart, but keep the key attractions delivering". Disney is the one making money however...
