as part of the proposal actions, after providing this liquidity, the protocol should market-buy some of the LUSD using FEI+DAI according to the current oracle price of LUSD. sometimes the LUSD price rises above $1 and if this happens then Tribe DAO will lose money to IL. otherwise this is just a donation to MEV / arbs. for FEI+DAI pricing is not an issue since their pegs are currently tied by the FEI PSM
what will the A parameter of the pool be? among other things this will determine the degree of IL for a given price of LUSD
