Despite the fact that this question didn't get further discussion, and
the fact that nobody seems quite sure what the best way of proceeding
here is, my interpretation of the comments made so far is that nobody
thinks that what we have now is superior to either of the proposed
alternatives, and there's a weak preference for v2 over v1. So I
committed that one.
