I agree with you. boost/<libname>.hpp don't needs to include all the public files. 
In addition to 
* typeof registration
* serialization
* phyton support

I will add every 'decoration' to existing types, either from STL or from Boost.

In Boost.Synchro I have files defining traits for thread mutex (from Boost.Thread) and for process mutex (from Boost.Interprocess). I as a user don't expect that boost/synchro.hpp will include all the traits files. IMO, it is up to the user to include the specific file.

In Boost.Conversion, boost/conversion.hpp includes all the core files, but don' include every specific STD or Boost conversion. If some one needs to use conversions from chrono::duration to posix::time_duration he needs to include explicitly

<boost/conversion/boost/chrono_duration_to_posix_time_duration.hpp>

Best,
