While this may be true for some (or even many) "core" Boost libraries, I
believe there are enough peripheral libraries that could safely be built
against multiple Boost "core" versions.
And while you may not yet want to consider separating the release cycles
of individual Boost libraries, I think it's a big error to design such a
restriction right into the infrastructure. Not being able to build Boost
libraries stand-alone (i.e., against a preinstalled set of prerequisite
Boost libraries) is one of my biggest complaints against the existing
(For example, I test and run development versions of Boost.Python
against various older Boost releases fairly regularly, but to be able to
do that I need to use my own build system, unfortunately.)
