We have it, in develop. I've seeded it with a few headers from utility that 
met the criteria:

- boost/utility/addressof.hpp
- boost/checked_delete.hpp
- boost/utility/enable_if.hpp
- boost/noncopyable.hpp
- boost/ref.hpp.

Of these, noncopyable.hpp may be a bit controversial, being arguably an 
end-user header and not a core utility. It is, however, used by the Type 
Traits library:

http://www.pdimov.com/tmp/report/type_traits.html#utility

along with enable_if.hpp and declval.hpp. enable_if is now in core, 
declval.hpp both uses and is used by Type Traits and will migrate there 
earlier or later, so moving noncopyable into core allows us to cut the link 
between Type Traits and Utility.

Next obvious targets: boost/iterator.hpp, boost/detail/iterator.hpp, 
boost/detail/lightweight_test.hpp, boost/cstdint.hpp (if it doesn't go into 
Config).

Then we probably need to look at

http://www.pdimov.com/tmp/report/mpl.html#detail

and

http://www.pdimov.com/tmp/report/mpl.html#utility

That last dependency, on value_init.hpp, I had missed. Oh well.
