Good idea.
I added it to the documentation on jbosstools-target-platform wiki: https://github.com/jbosstools/jbosstools-target-platforms/wiki
"3. Compare content of newer SNASPSHOT of target platform site with previous version, using p2diff. Keep track of the changes that were not announced earlier and send a mail with a summary of those changes. Such changes can be some refactorings inside features, that are not visible directly in the .target file."
