 ## Design
 
 The contracts are designed with a priority on efficiency and minimalism. 
 
-- Multiple input calldata arrays instead of an array of structs for more compact calldata encoding.
-
-- Omission of utility functions like `getBlockNumber` for more efficient function dispatch. If you need those functions, just add those functions into your contract, or read them off a separate utility contract like [MakerDao's Multicall](https://github.com/makerdao/multicall).
