For some reason I was not on this list;
So in response to your query about CF’s usage of CFGetRetainCount - I think we can safely forbid that function in the swift version since there is no safe way to use it (even CFMachPort is a bit dodgy for it’s usage).

It might take some surgery but I can probably excise that fairly simply.
