The AIFF spec states that programs should preserve chunks unless the
audio data is edited. If the audio data is edited, then there's no way
for a program to know whether the chunks are still valid for the new
audio data, and thus the spec recommends that they be dropped. I
don't know what operations you're running with the Apple Loops
utility, but it could be perfectly legal and recommended to delete
unknown chunks.
Too bad the AIFF spec doesn't have any way to distinguish chunks that
are tied to the audio samples versus chunks which would always be
valid even if the samples are modified.

Here is another thing I noticed about the 2.0.1 Apple Loops utility.
It deletes all other AIFF chunks that it finds. I put in a file that
had 3 user defined chunks, and the new utility deleted them all. Now
the AIFF spec states that programs should preserve chunks whether or
not the program need/uses them. Why does the Apple Loops Utility do
this? I found v2.0.1 apart from the SDK. It was in the Logic Studio
Installer. Is 2.0.1 canonical?
