Feature request from Steve Myers (who I chatted with this weekend at ONA):

need to get this off quickly before i forget it. one reason we moved our pubsked out of the cms was the possibility that others could see it in draft form or that we’d accidentally publish it. because pitches live in the WP admin as posts, you may want to think about disabling the “publish” function for posts that have the posttype “pitch” or similar content-planning types. and you may want to disable previewing for those kinds of posts.

I’m not entirely sure how this feature manifests itself, but I think the pain point is perfectly valid and worth solving.
