While I agree that the pdf format is superior than dwf, the fact is dwf (like dwg) is what a client specifies on some projects, so like it or not it must be supported. That being the case, it would be great if VW allowed import/export of dwf files. For us Mac users, dwf format is a major pain as few good (if any, really) exist.
In searching the posts, this has been asked for for a long time now, hopefully it gets incorporated.
