For things like CDP liquidations and interest rate adjustments which need to be done quickly, this cane be problematic.
Interest rate adjustments definitely do not need to be done quickly; once a week is fine imo.
For CDP liquidations, the idea is that you only need the process to start to put the CDP in limbo. The first liquidator would have to provide a lot of collateral to make sure the outcome resolves safely no matter which way it goes.
Also, it can be very dangerous if the assets under management of the oracle (how much can be stolen by the oracle lying) exceeds the market cap of the oracle token (UNI in this case) by 2x since it becomes profitable to rob the system via governance attack.
And this is exactly why I am proposing that the absolutely-massive-market-cap UNI takes on this task!
