I'm curious as to why the S-RF3 has an OLD 3mm short of a well established standard. It doesn't matter because there's plenty of axle, so you could always add a spacer if you want, and 3mm wouldn't make a difference anyway.
As to why it's 3mm short, 2 possibilities come to mind (speculation only). Possibly the hub includes an anti rotation washer which is 3mm thick and goes inside the dropout. Or they' left it 3mm short so you could add it back on either side (or split it) to optimize chainline. Either way, both hubs will work, and you can sweat the fine details when fitting one.
