I have not personally had time to look into it, no (I assume you meant
this for me, even though you addressed it primarily to Champan, who
previously did not participate in the thread). And apparently neither
has anybody else.

It should be noted that pglister does exactly nothing with it and
should pass it through without making any changes whatsoever.

The question is what happens when it hits the archives, which are not
part of pglister. Which of course still needs to be handled.

A first step would probably be to figure out *what* to do. The RFC
basically appears to punt on the whole idea of what to do with
multiple parents. I'm unsure what would be the best thing for pglister
to do. Just pick the first entry and go with that? That would
certainly be the easiest, but would it be correct?
