Is "Members" visibilty available anywhere in Videos resources in Youtube Data API?

One of the Videos resource's properties is status.privacyStatus. According to the API documentation, it can be "private", "public" or "unlisted". Those values match the possible values for the visibility of a video, except for "members", which does not seem to be available in status.privacyStatus property.

Two questions:

1. Is it correct to assume status.privacyStatus is the same as the video's visibility?
2. Will "members" ever be added as a possible value to the status.privacyStatus property?

I was expecting to see one more value available in status.privacyStatus: "Members"

Thanks!
