Request Specific Per-App Post Privacy Setting

So facebook just implemented this per-app post privacy setting for all applications as announced here.

There doesn't seem to be any documentation of any sort on it besides that blog post.

I'm interested in explicitly asking the user for a specific setting. Right now it appears to default to ALL_FRIENDS, but my app currently posts with a privacy setting of EVERYONE.

In fact, my application broke because of this change; I only discovered it through asking this question.

Is there any way to ask for a specific post privacy setting (in my case Public or EVERYONE) on login, similar to how we a开发者_开发技巧sk for all other permissions?

Well, after checking several applications, it seems that they've changed the default setting back to "Public" for new installs. I looked at some Zynga applications and there doesn't seem to be a way to specify which level of privacy of the apps postings. (if anyone has info on undocumented features, it's Zynga) I also don't see any way of querying to see what the user has set it to.

edit: did a little more testing... It seems that the default is dependent on the account. It appears to be the same access as the default offered when you make a wall posting.
