That is true.

After the transition to Git, Boost.Exception will live in its own
repository. People might be bothered to have this repository as a
dependency, even though they have exceptions disabled. So we are
really talking about library dependencies, not include dependencies.
Moving throw_exception.hpp out of this repository eliminates that dependency.
Also, that header should not include any headers from Boost.Exception
when BOOST_NO_EXCEPTIONS or BOOST_EXCEPTION_DISABLE is defined.
