Comment (by azaozz):

 Agree with @nacin.

 The discussion started in
 http://core.trac.wordpress.org/ticket/23198#comment:10 as this was
 discovered there. Initially get_post_format() was returning WP_Error
 coming from the lower level API [15777]. Later on we improved it to use
 better low level API that wasn't returning WP_Error any more [16319]. So
 for over two years this function has been returning either `false` or a
 string.
