I have been paranoid about this, so I check every few weeks to see if they got restored secretly (I used a script to first overwrite and then delete all of my contributions, about 4k comments and a several OC posts).
So far it seems to still be deleted

I don’t think this was true. The actual issue was you couldn’t see posts you’d made to private subreddits. Once those subreddits reopened, it made posts visible in their profiles and made it look like they hadn’t deleted everything.
