It's really useful to have a composited z channel. With the deep samples having front & back, there's no obvious answer for how to exactly do that, so I usually just take the midpoint depth of each sample and composite that value just like another color channel. This isn't perfect, and suffers from all the problems that non-deep-depth always suffers from, particularly in the presence of volumetric data - but it works well as an input to functions that need a single depth.
