Hey Marc,
Good question. LDO is a governance token for now. We are exploring future V2 use cases as collateral in a staking module to allow anyone to validate the protocol. That is still in development.
We are often asked about additional activities in DeFi by LDO holders, and lending makes a lot of sense from our perspective. Euler already has a small but active isolated market for LDO.
With users of custody platforms, they can interact with defi but cannot participate in on-chain governance. I think this is a partial step to adding more functionality besides buy/sell/hold for that cohort.
Maybe even eventually allow aLDO to vote in governance
