I think it’s not expedient to discuss specific changes to the DAI market, as the problem is not a specific DAI market problem.
The root cause is, that the open oracle, which Compound uses, has got only one source, which is Coinbase. This means, exactly the same problem can happen to any other Compound market (beside the the markets with a fixed USD value). Imo for that reason the solution can only be to fix the Compound oracle problem.
