Ease life to plugins wishing to extend post type tracking

[imath]

BuddyPress only deals with the 'publish' new/old post status to eventually add or remove the activity generated by post type activities.

I know (i've experienced it with one of my plugin) there can be cases plugins can need to add an activity for private posts eg: a Groups component wishing to attach private activities corresponding to private post types (or any other custom status).
