Comment:

 @wonderboymusic That's probably because there still are no tutorials on
 how to use the new Backbone API in plugins. The compat fields generated by
 `attachment_fields_to_edit` are huge mess markup-wise and behave
 completely differently because they get thrown into a `<table>`. I'm in
 the process of converting my plugin (Media Credit) to the new API and
 while it's possible to override yet another method on the JS side, it
 would be far nicer to be able to hook in to the existing
 `wp_ajax_save_attachment` action.

 On a not-so-thorough first reading of the code, I thought I could use the
 existing `wp_update_attachment_metadata` filter for this - until I noticed
 it is only called for attachments of type `audio`:(
