I don't know if this feature can already be achieved by some other module (my searches were not successful), but I currently have a project that could use this and this module seems like the place to ask for it.

An example use case is when one wants to set a "notify subscribers for content change" flag for example. This flag would not make sense when creating a new node of that type because a) the node does not have any changes or previous revision - it was just created and b) there are no subscribers to the node yet because it is not even saved.

PS: another module I thought to file this feature request against is conditional_fields and its related projects, but these rely on the status of other fields - not on the status of the node.
