 ### Still pending
 
-* Rename `agreementId` to `voucherId`?
+* Make `agreementId` unique globally so that we don't need the full tuple (`payer`+`indexer`+`agreementId`) as key?
 * Update `DisputeManager` and Arbitration Charter to support disputing Indexing Fees.
 * Support indexing agreement upgadeability, so that there is a mechanism to adjust the rates without having to cancel and start over.
 * Built-in upgrade path to indexing agreements v2. So that indexers can be paid per byte instead of per entity.
