"RMS: For the case in which the RMS value of a full-scale square wave is
designated 0 dBFS, all possible dBFS measurements are negative numbers.
A sine wave could not exist at a larger RMS value than −3 dBFS without
clipping, by this convention." -

I can't say anything about CD quality and the need to use a margin as
close as possible to 0 dBFS, but for DAT quality there is no
need to be close to 0 dBFS, OTOH it also doesn't cause audible issues,
if you master up to 0.5 dBFS. Headroom doesn't harm, OTOH if a demo
recording isn't as loud as other demo recordings are, this might be a
disadvantage, since not everybody knows how to use an amp's volume
