Two things:

 - Your plugin will probably become a lot simpler if it is updated to use
the newer post type UI/API.

 -  We are still doing backwards compatibility sweeps. We will continue to
support attachment_fields_to_edit in a backwards compatible, deprecated
fashion, it just doesn't yet. Thanks for the reminder on this hook in
particular.
