You assume that we will never want to use this kind of infrastructure
for any other variables?  The fact that we currently use this only for
2 variables doesn't mean it doesn't have a more general value, or that
we introduced it for those 2 variables alone.

Perhaps if you explained the general idea of the changes, I could have
answered these questions myself, but as things stand, I don't think I
understand how important this patch is for the general purpose of the
series -- just one example of where a more detailed overview could be
of value.

Thanks.
