Thanks for looking at this. I am wondering if there is a reason why the tp_alloc can't be replaced with the PyBaseObject_Type->tp_new directly? My understanding is that initially, object's tp_new essentially just called tp_alloc as Cython does now. Later the abc feature was added with the abstract check happening in object's tp_new, while not changing previous (non-abstract class) behavior. If Cython were to use this instead of tp_alloc, it would be forward-compatible with future changes to object. Aside from your comment that it would need extensive testing, am I missing some other problems?
