As I clean up Python/import.c and move much of its functionality into Lib/imp.py, I am about to run into some stuff that was not kept private to the file. Specifically, I have PyImport_GetMagicTag() and NullImporter_Type which I would like to chop out and move to Lib/imp.py.

From my reading of PEP 384 that means I would need to at least deprecate PyImport_getMagicTag(), correct (assuming I follow through with this; I might not bother)? What about NullImporter_Type (it lacks a Py prefix so I am not sure if this is considered public or not)?
