Autoblog 4+ Post Formats Add-on

Using Autoblog 4+ (4.0-4.06), the Post Formats Add-on appears non-functional; there is no Post Formats option in the feed item admin form. Tests conducted with the initial release of the Post Formats add-on from 3.5.5, even when copying it into Autoblog 4.06, at least correctly show up in the feed item admin form (with PHP warnings) below the "Set the date for new posts" dropdown. At some point, a rewrite appears to have occurred... and the feature appears to at least be partially broken and will not appear in the feed item admin form anymore.
