It's definitely an RPM bug, just one that is really, really hard to fix. (IIRC it's due to a limitation in cpio, so fixing it would require changing the format files in RPMs are used to something else, which is...quite the undertaking.)
I don't see why using the cpio format makes it difficult to fix this. rpm can't be just forking off cpio, and feeding it the payload inside an rpm file. Otherwise there's no way to implement %noclobber.
rpm must be parsing the cpio format manually, and doing extraction by hand, one file at a time, in order to be able to do %noclobber, and a few other things.
