If the contract doesn't specify something, then the only thing that's
safe to assume is that it's not supported.
I'd argue that implementation details shouldn't influence higher-level
design if the contract is well-specified. Although, it's probably
unavoidable that it happens---but, you want to make sure that your
design doesn't *depend* on an implementation detail that's not
specified in the contract.
