The nice thing about the newest books API is that provides a single call for all necessary data. OB3 moved to this api for that reason, helping to resolve performance problems that came from making additional calls. I'm not sure I would want to build extra calls and looping in my client code to resolve what is really a data duplication issue. That said, I guess it would be better to have some cover than no cover.
