Not sure what you are asking: I assume you are not asking about new type objects (as created by typeobject.c:typenew), but instead about instance of newstyle classes (i.e. instance of type objects). Correct. Why would you then think that using PyObjectNew is a bad thing?

IIUC, PyObject_New doesn't call the tp_new, tp_alloc, and tp_init slots. So, the new object probably will be in an invalid state, may be allocated by an allocator not compatible with the tp_dealloc slot?
