Some assets (eg. staking derivatives like rETH and wstETH) that can be supplied on AaveV3 Arbitrum do not have direct USD price feeds. The current implementation lacks support for such assets.
wstETH, for instance, is the 2nd largest supplied Aave asset on Arbitrum, but only the wstETH / ETH exchange rate is available. It would thus either require a composite price feed that complies with the AggregatorV3Interface, or rely on the fallback oracle.
