Unpublishing multi-language nodes - no ContentUnpublishedNotification until last language

Questions

Hi,

When clicking “Unpublish” and selecting one the available cultures of the node, no ContentUnpublishedNotification will be caught in my handler until the very last culture is unpublished.

No notification sent once the first 2 cultures are unpublished:

Once the last culture is published, a notification is sent:

How do I find out a culture has been unpublished then?
Is there a different notification for culture modifications?
