This Proposal is for chain selection feedback for the ongoing proposal https://snapshot.box/#/s:uniswapgovernance.eth/proposal/0x675c9697cc6c8d1cab27e1cffab3fdc7740b3e978eb37d8b6dcce76d1726670f so it depends on whether the proposal Analytics Hub for Uniswap’s Revitalization and Growth Program passes.
For Unichain option, as the incentive is ongoing but as there’s a lot of interest, it’s listed as an option so that the community can see level of interest but from ranking for Forse for this proposal, it won’t be counted. So even if Unichain is among the top 4, it will skip it to include the next one into top 4. But Unichain related proposal could become its own RFC in the future if it's highly in demand.
