I agree.

current_function.hpp seems to be purely 'config' related, in that it just detects different compilers and how to determine the current functions name.

assert.hpp doesn't depend on anything other than config and current_function.hpp (which would also be config based on the previous point), so whether this goes into it's own library or config probably doesn't matter from a dependency perspective.

ref.hpp going to Bind makes sense and would improve things.

checked_delete.hpp and addressof.hpp are both similar in that they only depend on Config and there has been some discussion of having a repo/library for things that don't depend on anything but Config (perhaps called Core), but that hasn't happened. Though, I'm not sure about using that for user visible things, like this.
