To clarify the record, the DAO did not allocate treasury funds or guarantee repayment to affected sDOLA borrowers.
The sDOLA proposal authorised a fundraising gauge through which veCRV holders can voluntarily allocate gauge weight to direct future CRV emissions toward remediation. Of the events you mentioned, only the Vyper hack received funding from the DAO treasury.
If you believe the CRV-long market warrants the same fundraising mechanism, or have another remediation proposal, you are free to submit it to the forum and, if it receives sufficient support, advance it to an on-chain vote.
