On second thought, I’m not sure if I would include this on the interface id computation or not yet, because I don’t know if we need to encode `self` somehow in calldata when using `call_contract_syscall` for calling a contract implementing this interface. If this doesn’t need to be encoded, I wouldn’t add the `self` type to the interface id. Need to check with the compiler team.
