So far, the CCZ4 formulation has only been tested with the W conformal
method. In principal it should work, but given that it hasn't really been
tested it is possible that there are bugs. In this case, this looks like a
bug to me and this term should be different if the W conformal method is
not used. Given how close we are to a release, should we just add a note to
the release notes (or elsewhere) stating that only the W method currently
