I think many software engineers could get benefits out of learning some project management skills, but I must say I'm also skeptical of the benefits they'd get from more theoretical knowledge of project management in themselves. But I also have an immediate reaction to the term "body of knowledge" in the context of PM, which is to reinterpret it as "cargo cult." Hopefully they have something different in mind here, but that's often what it ends up as in practice.
