Oven owners could be allowed to opt-in to a sort of liquidation pool with their ovens.
kUSD can be minted from their excess collateral up to a certain point (say 250% ratio) and pooled together automatically to liquidate large ovens.
In effect, at a 200% collateral ratio, they would be agreeing to mint kUSD and trade it for XTZ at 50% of harbinger price if necessary.
Is this possible? Is this a realistic solution to the large oven problem?
