Comment:

 Although this is new in this location, it's not a new notice, you'll also
 see this in the Publish metabox for unpublishes CPT's, and probably a few
 other places.

 WordPress assumes that certain capabilities will be set, `delete_posts` is
 one of them. I'd suggest that instead of adding isset() checks, we should
 pre-define these as `do_not_allow` in `get_post_type_capabilities()` when
 not provided by the CPT registration.

 I'm shifting to 4.2 based on that, as this doesn't cause any negative
 issues, and is really a good reminder to developers to assign capabilities
 when they're not using the builtins.
