We may, that was my initial suggestion in this thread, then I have tried
to discuss if it would be simpler just to call them modules, and define
that a boost library contain one or more modules. In some ways I think
that is simpler, but I am not sure it is clearer or more natural.

One problem with "Boost sub-library" is that it is deemed to trigger
questions of whether they have separate maintainers, have been
separately peer-reviewed etc. While a boost module is simply a
structured part of a boost library.
