I'm not entirely convinced of the CPANForum's usefulness (unless it has some way to automatically email the registered owner of a module each time a question about it comes up or something, and then, of course, a way for each author to tell it to go away and stop bothering them). But adding it here? That is just as bad - and since CPANForum already exists, it's actually worse (compounds the problem rather than fixes it).
As for using Perlmonks Discussion as a place for discussing modules - that seems wrong to me, too. This is about discussing perlmonks, not modules (that's what SoPW is for). Which, I suppose, makes this particular thread on-topic here, but what the thread is about would not be on-topic here, IMO.
Any "reformulation" for here ... could just as easily be added to CPANForum. The question is, is any author going to pay attention to here any more than CPANForum? I doubt either one has an edge.
