I find it encouraging that you commented on the choice of name. :-) I can live with PyType_FromMetatypeAndSpec and leave out bases.  PyType_FromTypeAndSpec is fine too. 

On the substance, I don't think this API is just convenience.  In my application I have to replace meta type after my type is created with PyType_FromSpec. This is fragile and works only for very simple metatypes.

Let's get back to this discussion once I have a ctypes patch.  I there will be a work-around for ctypes it will probably work for my case. (My case is a little bit more complicated because I extend the size of my type objects to store custom metadata.  Ctypes fudge this issue by hiding extra data in a custom tp_dict. )
