There definitely is !

This seems to me a rather academic question, in contrast to the original
request. Boost is still shipped as a single package on most (if not all)
platforms, and providing some help to packagers to be able to split it
up would be extremely useful.

Whether individual libraries are header-only or not isn't all that
relevant in this context. If I'm building software that requires some
parts of boost, yet I'm not packaging it myself but instead rely on
external packages, I'm quite concerned about what other implied
prerequisites this may drag in.

Any work in this direction would be very much appreciated.
