Data Migration D.7.0.4 Beta

Testing the new D.7.0.4 I see there are still major issues with the data migration module. Why is it that it still does NOT migrate all data? Like avatars,polls...and so on and so on??? Are you guys planning on fixing this so we can just have that simple click and data is transferred, instead of having to manually move a lot of data ourselves? And even when all data is moved annually, somethings will not go back into place where they should be..such as the avatars.
