I did not upstream that part, because it requires third party code.

Can you create a bug to add this dependency to third_party upstream and link it
there.
BTW, could you please put a space after the # sign?

Do we really want to create individual bugs for upstreaming? Or can I use a
generic "upstream iOS code" bug?
