 This is a really bad idea. The whole point of using an enum is to have a
 fixed set of values that are valid ones. They are stored as integers
 internally and make things somewhat speedier, since WordPress selects
 posts based on post_status more or less constantly. Changing it to a
 varchar would create a not-insignificant performance loss.

 If a plugin is making such a radical change as to require its own special
 post_status values, then it should be able to take the time to alter the
 table to allow that status.
