Ah, I remember now, that we talked about that. My bad, I had forgotten
during the review.

However, we can't really change the implementation now, we're frozen for

What about adding this to the manual for now, since it does reflect the
current status of the code, and switch to an architecture option in
-next, or after the release is cut?
