I'd say that you were right, if not for the fact that we just tested the
migration successfully on sandbox, and so should be running that migration
on Freebase in the near future.  Note, also, that "included types" are not
retroactive--i.e., adding politician as an included type to US President
would only affect future presidents, the likely candidates for which are
probably all typed as politician already. :)
