Comment(by nacin):

 Another issue I see is that a plugin may have been using meta capability
 handling via capability_type = post but only partially. i.e. they mapped
 edit_posts to edit_movies and may have handed that on their own, but then
 let delete_post take its course. (Very similar to the OP.)

 At that point, we'd need fine-grained control for map_meta_cap, not just
 on/off, but rather on/off for read, edit, and delete independently. That
 seems silly.

 Other than a decision on
 [attachment:14122.remove.post_type_supports.author.diff], I am inclined to
 let this sit, and wait for bug reports once beta is out.
