While there's much truth in your statement, I wouldn't be so quick to discount the knowledge and experience of archivists, who have collectively as a profession put a tremendous amount of time and effort into researching archival theory and practice, both physical and digital, and who count among them extremely knowledgeable technologists. They are acutely aware of the fact that you can't just burn a cd and call it a day. With that said, I don't know anything about the Digital Preservation Coalition; you may be right about them in particular. [Edited for clarity]
