Why are we deprecating something rather than just deleting it and
fixing any users?
If the point is to keep the overload but prevent it from being called,
there are better ways than a deprecation warning.
And if we *really* needed deprecation warnings, I suggest using the
C++14 [[deprecated]] attribute (after adding it to the approved new
feature list). But I think we shouldn't be doing this at all.
