Yes, it can be envisioned, but has not been implemented, at least not
to Boost standards. That's exactly what I meant. Let's go back from
the general to the specific. Why should this specific library be
treated differently from other libraries for which a more generic
framework might be envisioned?

Yes, I think the fact that so far none of those several attempts have
(to my knowledge) been successful in dealing with the exception-safety
issues is good grounds for not delaying other libraries based on the
speculation that it can be done.

And you claim that having a PBSP would significantly reduce the
testing, publishing, and support efforts for this library? Have you
taken a close look at the implementation, or are you basing this
assertion just on the fact that it's a smart pointer?

Whose effort are you claiming would be wasted?
