Is it the reason for this to boost the 'boost' library adoption?
It is one reason, yes.
Another reason is that the C++ bindings haven't really delivered what
was expected. They were intended to be the baseline for implementing
higher-level C++ abstraction (such as boost.MPI). But that didn't
really happen -- the C++ bindings don't give enough extra
functionality to be useful to a C++ programmer in this regard. This
is the key reason that the Forum is voting to deprecate the C++
bindings: people are simply using the C bindings instead of the C++
bindings. That Boost.MPI is implemented on the C bindings instead of
the C++ bindings speaks volumes to this effect. :-)
