We do need to know what you're proposal is for.

(For practical reasons, RCObject will implement IUnknown. There are a
few random consequences of that (meaningless method QueryInterface, no
class info, no monitor, COM-compatible layout) but IUnknown already has
AddRef and Release and the compiler already recognizes IUnknown as a
special case. Hooking RCObject there will leave us with two roots
instead of adding a third one.)
This is actually a nice choice since COM would then (eventually) benefit
from whatever automatic ref-counting we embed into the compiler.
This is exactly what Visual C++ does now for new style COM object
(inherited from IInspectable).
Specially important since all new Windows API since XP are mostly COM based.
