OpenZeppelin maintains a library of standard, audited, community-reviewed, and battle-tested smart contracts. Instead of always importing these contracts, the protocol project re-implements them in some cases. This increases the amount of code that the protocol team will have to maintain and miss all the improvements and bug fixes that the OpenZeppelin team is constantly implementing with the help of the community.
Consider importing the OpenZeppelin contracts instead of re-implementing or copying them. These contracts can be extended to add the extra functionalities required if need be.
