Why is lack of data or visibility on this a problem for you?

Sure. Let's say library Boost.Library today depended on Boost.Core for
boost::addressof and Boost.TypeTraits for boost::aligned_storage -
tomorrow and both Boost.Container and Boost.TypeTraits choose to break
C++03 compatibility: Tomorrow, if Boost.Library's maintainer is still
interested in supporting C++03 users, they will just provide the above
in boost::library::detail::addressof and
boost::library::detail::aligned_storage (either from the existing
implementations or their own).

i.e. Even if we announce any such thing, it is still up to the
maintainer of Boost.Library to drop C++03 support. This might help
push them in that direction if they don't want the maintenance burden
sure, but it is no guarantee, especially if their users are more
important to them.
