I understand that they can exist, but for the waveform to be rendered
by the D/A, 3dB over the sample values (in the peake between the
samples) seems like an unlikely transient. Further, if the D/A has
sufficient headroom (modern good D/A should) I would think it's not
really a problem.
I still see plenty of mastering engineers normalizing their INCREDIBLY
LOUD mixes to 0, and to -.1
So in short, I tend not worry about it. :-)
