PyType_FromSpec() and PyType_Spec API are not currently compatible with opaque PyObject.

Example:
---
#define PyObject_HEAD    PyObject ob_base;

typedef struct {
    PyObject_HEAD
    ...
} MyObject;

static PyType_Spec type_spec = {
    .name = "MyObject",
    .basicsize = sizeof(MyObject),
    ...
};

... = PyType_FromSpec(&type_spec);
---

sizeof(MyObject) requires to compute sizeof(PyObject).
