Should I Read Petri and Hahn?

Over on Crooked Timber, Michael Greinecker asserts without argument:

Sraffians are actually debating about non-problems. The standard GE model is a strict generalisation of the classic one. They simply don't get it, as they have proven at a conference on this very issue. The people who are really into aggregation problems are theorists like Kirman and Hildenbrand.

I find Petri (2004) cogent and well-argued. But given the references in the introduction to my draft paper, "A Model for Exploring Manifestations of Capital-Theoretic 'Paradoxes' in Temporary Equilibria", would I learn anything new by reading the proceedings in the volume edited by Petri and Hahn? This paper also shows why I don't find it convincing to say dynamic equilibria (which I take to be the same as temporary equilibria) are immune from Sraffian criticisms.
