Please, something important to add is the important warning in comments that OZ just added it in this PR https://github.com/OpenZeppelin/openzeppelin-confidential-contracts/pull/276/files, it is not yet merged in their repo, but I really feel it is necessary to avoid confusion later for new devs coming to fhevm, especially since this contract will hold significant money amount and will be one of the first references of fhevm on mainnet.
I would also add this other pending PR for overriding EIP165 function https://github.com/OpenZeppelin/openzeppelin-confidential-contracts/pull/267/files but this one is less urgent.

since the PR is still on-going and introduced several changes like introducing the interface for the wrapper, I think it's best if we do this later since it's not fully urgent !

created https://github.com/zama-ai/fhevm-internal/issues/814 for that matter
