That would not achieve what Romain wants. Or rather, it would when he did
it, but would not be guaranteed to do so at any point after the next
release of R.
My understanding of his request is that he wants something that will
"behave as R will", not "behave as R does now".
All that having been said, not every single thing R does internally can be
public and of course I'm not privy or a party to discussions on what should
and shouldn't be. But freezing and duplicating small pieces of R's
non-exported internal code seems like a dangerous move to me.
