That would make the wrapping code easier, since the storage of the wrapped C-Reference could all be done in the CFType wrapping code. Additionally there are the C functions CFRelease and CFRetain which you can use with any XXXRef type instead of the more specific CGImageRelease, CGContextRelease functions. Currently it would be very hard to implement the generic functions, since all CGXXX classes store the wrapped C reference in different members.

From my part, I agree.
Just the line 

Derived from CFType Reference

is enough to convince me that this is the way to go.
