So... how is it useful? You're trading one oracle for another. Either of these oracles can be manipulated or compromised.

I think one could argue that it's more elegant from the point of view of blockchain maximalism. But I don't quite understand the utility in any other sense.

It's useful because it's coming from the original source, instead of having an oracle network made up of 3rd parties which vote on it.
