The problem is that what I want is so much simpler than subclassing.

>>> orig = object()
>>> orig.foo = 5

>>> newobj = object()
>>> newobj.bar = 6
>>> newobj.__fallback__ == orig
>>> print newobj.foo, newobj.bar
(5,6)

I don't claim that this feature would save me so many hours as to even
justify the amount of time I've spent explaining it. It just struck me
as being in the same category as, for example, importing where you see
the language do something magical (finding a file and loading it as a
module) and then find out that the magic is based on simpler concepts
that are each independently available and overridable.
