I want to use an additional, arbitrary post status on one of my custom post types. I'm calling it "limbo", and it's assigned to a post which has been deleted by the user, but one that I still want to keep its data on the database for legacy purposes.
I assign it to a post by hijacking the permanent deletion routine, which is to say I'm not really registering it via the proper WordPress function
register_post_status, because a) it's not something I want my users to worry about or deliberately assign to their posts; and b) it's only applicable to a single custom post type, which I cannot specifically target with
I don't feel confident that it's the most reliable solution, though.
Is there a routine check that WordPress would run on the database which would detect this invalid post status and revert it, or am I being overly paranoid?
Either way, is there a better solution which wouldn't rely on full-blown plug-ins like Edit Flow?
