[TEMP CHECK] Add FXS to Ethereum V3
Vote Result: YES
Rationale
FRAX is a well-known pillar of DeFi and an ecosystem unto itself. FXS is a core part of this ecosystem and allowing it to be used on Aave will be beneficial for both protocols. Gauntlet is in favour and there is also broad community support. Moreso, FXS earned from the Aave V3 pool can be locked as $veFXS as a new strategic asset to be used to bootstrap GHO and/or new aToken adoption. Therefore, we are in favour of this proposal and will vote YES.
