That's completely irrelevant. Let's just step back a bit. You started 
this by saying:

I am simply pointing out that RPython is used for efficiency, not to do 
things that can't be done in standard Python. Since everything that is 
done in RPython can also be done, albeit more slowly, in standard 
Python, the claim to be self-hosting is valid despite your disagreement.

In other words, you can take the PyPy translator and run it on CPython. 
The fact that they choose to use restricted Python instead in their 
"production" system is merely an optimization.
