Not including CMFDefault is entirely reasonable. There are two problems
though:

- CMFDefault is in the Products namespace, so five will load its zcml
  automatically.

- some of these are in CMFCore (handleDynamicTypeCopiedEvent for
  example, which zaps local roles from copies). Asking people to
  copy CMFCore configuration for a reasonably common use case is
  not desirable imho.
