That stuff started out almost as an experiment and was intended to be
generally usefull for all sorts of container classes.
In particular, I figured that it would make perfect sense to have that
functionality available in Boost.Variant.
However,  when I talked about it with Eric Friedman, the Variant author, he
expressed reservations so he never used it.
I figured that we would eventually discuss it and shape it up to its final
acceptable form.

That never happened and the factories ended up in the release undocumented,
and worst, unreviewed. A mistake of course.
Fortunately, they seem to fulfill their intended purpose, at least with
Optional.

No rationale, just sloppiness.

Yes.
I'll start fixing it right now.
