"- Both prosopagnosia and alexithymia are more common than autism (though we seem to have misjudged the commonness of autism by quite a bit)

- Both conditions are very common but not universal in people with autism.  Are the a result of autism, or are they independent?  No one knows.

- The close association between them suggests that autism, prosopagnosia and alexithymia may share some common causative factors; even that one may cause the other in whole or in part.

I’d be very interested in studies that looked more closely at prosopagnosia and alexithymia.  They are two under-studied conditions that might shed some light on the mystery of why we are the way we are.
