Abuse deterrent C-II

Just to be clear...are any of the C-II opioid generic abuse deterrent? My knowledge and research suggests NOT and FDA are in the process of releasing a guidance for the mftrs to make such. On the similar note, I wonder then why we can substitute Oxycontin with oxycodone ER since Oxycontin is abuse deterrent and the generic is NOT ?
