I hope you do realize that my own comments are not even remotely a
criticism as to how well config has worked or your incredible job at
keeping it as good as it has been. Nor do I think, from what I know of
config, that the actual design logic of config has to change. But it may
be that I am not seeing the many complications that you foresee.

I hear that. I think that is why Peter's suggestion, which may have been
considered in general before as an idea, has never seriously been
considered in actuality. Getting it right must be perfect, else the rest
of Boost will be greatly messed up.
