Per Pashovs audit report, L-04 mentioned that the unused EthenaMinting::encodeRoute has been removed by Ethena. However, this erroneous function still exists in EthenaMinting.sol. 
https://github.com/code-423n4/2023-10-ethena/blob/main/contracts/EthenaMinting.sol#L334-L336
Consider removing this controversial function where possible. 
FJ-Riveros (Ethena) acknowledged
