Let me rephrase:

Just looking at detail we are evidently duplicating files rather than
creating symbolic links to files.

For instance in libs/detail, which is a submodule, we have
libs/detail/include/boost/detail/allocator_utilities.hpp. In
boost/detail we have allocator_utilities.hpp. They are separate files
but with the same text. Let us suppose that the
libs/detail/include/boost/detail/allocator_utilities.hpp gets updated in
git. When this happens, how is the boost/detail/allocator_utilities.hpp
supposed to be updated if it is an entirely separate file ?
