Yes, and if you break it you pay to fix it. Are the tiny possible fuel savings from covering the exhaust worth the risk of killing a harness and sensor that likely cost hundreds of dollars? That is for you to decide.
Manufacturers are risk adverse. We do millions of dollars of testing to reduce warranty costs and also have very little tolerance for warranty issues. At my company a 1% failure rate will get a problem escalated to the CEO. For any company a 4% failure rate on a powertrain or emission item triggers a mandatory recall.

Steady state can be easy or a pocket of still air can cook components. I've seen it happen.
