I know who you mean, but as I wrote above: I would do that/maintain the texts if the work isn’t too much. 
I don’t think that this is a problem. My version history is a wiki post and no one has messed it up - yet.
The problem is, that you can’t edit the posts after a while. So what happens if we have to rewrite parts of a text? After the post is locked we would only be able to track the edits in the comments below. And …
… this could lead to the situation that the person can’t edit “coming soon” anymore. So the person has to keep “coming soon” in the first post and post the podcast text in the comments below. And shouldn’t we publish the auto-generated texts as a help?
