If u put it the other way around, one gets Boost.Serialization included if using
Boost.Filesystem (technically this may depend on the actual headers include, but
from a conceptual point of view). Imho Boost.Filesystem is a basic concept,
representing a path (instead of using raw std::string's), so I can imagine in
time that e.g. iostream and Boost.Serialization uses Boost.Filesystem when a
path is used in its interface.
Same argument goes for Boost.DateTime (as being a representation of a c++ date

Agree, but it wasn't put in the smart pointer library for good reason?

Fwiw if u need a concept which uses library A and library B, there is always a
question where to put it (i.e. in library A or B). I would model it like layers,
where higher concepts are dependent on more basic concepts. If library A and B
are equal in that respect, one could go for a new layer. In practice that could
introduce a Boost.Rest (or Misc) library?
