The one thing I'm not 100% certain on is if HDCP revocation list updates go through BD+ or if there's a separate mechanism for those updates. However, BD+ code gets to inspect your player software and modify it, which is sufficient capability to do updates, even if they don't use it for such.
I also don't know if they continue to release updated BD+ code or if they've given up on that.
