I support the concept, but the proposal has some basic errors that should be clarified:
aTerra does not exist. I assume you mean aUST.
aUST does not exist on Ethereum. The easiest way to access the Anchor rate at the current time is likely via Orion Protocol. The suggested TAP-5 covered this approach for FRAX, and the same principles apply to wUST;

I suggest we have the policy team review and whitelist Orion itself— not just Anchor. Orion injects an additional later of smart contract and liquidity risk, but is the only practical way (that I know of) to access the Anchor rate for wUST (ERC20) tokens which is what we have in the Olympus Treasury.
Happy to be corrected if there is an alternative approach the OP intends to use to access Anchor from Ethereum.
