Hey Larry,

It's common to pre-comp work you're doing while compositing, or to work in
stages. By not requiring a Deep Pixel (in Nuke, or in EXR2) to be "tidy",
it makes merging deep pixels trivial, as well as keeping the amount of data
significantly lower.  By way of example, look at how the deep pixels in the
paper have more points of data after being tidied. Peter Hillman had some
specific examples showing how tidied volume renders became significantly
larger than their untidied versions.  Since the major downside, or
limitation, of deep workflows is their increased data usage - every step
which can prevent additional data bloat is one we should take!

Given that the paper provides a performant code sample which will tidy and
merge samples, one that can be used by client applications, is this a major
concern?

I think this situation absolutely requires that a really futile and stupid
gesture be done on somebody's part. And we're just the guys to do it.
