A report of this nature could be useful to help inform future iterations of CoW Swap, therefore I support this proposal in principal.
However, the budget breakdown and completion bonus will require modification.
I suggest that the 21k USDC payment for the report is made in two payments, one being upfront, and the other half upon completion and acceptance, reducing counterparty risk.
The Completion Bonus of 180K COW also seems abnormally high for 6-8 weeks of work, as a payment of that much COW has historically required a DEX to supply ~100M in volume to CoW Swap.
I will be interested to hear the views of the other grants committee members regarding this proposal.
