I don't have a technical answer to give you, but if the recommendation is to work at around -23 dBFS RMS, I would agree that this is sensible. If you establish your "0 dB" point at -23 dBFS, you have an amount of (digital) headroom that's approximately what you would expect in a traditional (analog) mixing desk -- more than 20 dB above your "0 dB" point before you completely run out of voltage rail. The only problem is that most DAWs use a default style of waveform display which makes it hard to even tell there's a signal at that level.... you have to get up to about -10 dBFS to be able to see the shape of the signal's dynamics...
