[boost] [modularization] Are modular releases a goal or a non-goal?

Hello, I can download one monolithic tarball to get Boost 1.56: http://sourceforge.net/projects/boost/files/boost/1.56.0 And I get all of it. There are no separate 'modular Boost' tarballs so that I can download what I want and not what I don't. Compare to Qt which provides both monolithic source tarballs: http://download.qt-project.org/official_releases/qt/5.3/5.3.2/single/ and modular source tarballs: http://download.qt-project.org/official_releases/qt/5.3/5.3.2/submodules/ Is something similar to this a goal or a non-goal for 'Boost modularization'? Thanks, Steve.
