CS contains some rudimentary helpers for crash handling and minidump writing on Windows. However,  Breakpad provides the same functionality, is cross-platform, already comes with helpers to facilitate crash report upload to a server, a server-side report submission software, and is more likely to be reliable (since it's actively used in production for FF3). Thus, probably ditch CS' custom crash handling stuff and point people who wish such functionality to Breakpad (or even utilize it ourselves for demo apps).
