Well for me I do not see a need to change the original WCF, et. al. However, it does not directly address many of the theological problems seen today: NPP, Feminism, Postmodernism, etc. However, is it even suppose to?

IMO the WCF and the other historic documents are general statements of the faith and are not meant to directly address these concerns (though they somewhat do if properly interpreted). Thus, IMO a Reformed Apologetic Appendix may be discussed where certain heretical doctrines (syncretic--fusion of Jewish or pagan with Christian elements, formatory--when the Christian faith is being formulated, undue emphasis may be put on one aspect, and thus a statement of truth may result in error, and anti-ecclesiastical--against the Reformed church, its theory and its practice, etc.) are listed, discussed, overthrown, however not appended to the WCF, et. al. In other words just create another document addressing these concerns and to which future additions may be made. I think it would be great to have a document focused on such issues.
