BIP 000X: Babelfish Basket Balancing

What does ‘calculate reward in XUSD’ mean? Are you implying rewarding users with additional xUSD if they contribute to under-weight pools?

I’ve asked this question a couple times on disparate channels and it’s possible I am not comprehending but why wouldn’t we just fork Curve’s stable swap mechanism?

Couldn’t xUSD just be one large CurvePool that trades amongst its self. That would auto balance the pools, it would generate fees and we wouldn’t have to worry about added risk of lending stablecoins and insurance funds, etc.
