The templates `MutableOf` etc in std.traits – they don't seem

Except for `MutableOf` they are all currently public and even
the `package`- level `MutableOf` is publicly documented. All
this seems pointless.
Of course they are used in the implementation of std.variant
but for that they all can be marked `package` and they don't
need to be publicly documented.
They are also used for making the internal life of QualifierOf
easier, but QualifierOf itself is not publicly documented.
Is QualifierOf intended to be publicly used? What is the
difference in final utility between QualifierOf and
CopyTypeQualifiers?
Thanks!
It might be better to ask in http://forum.dlang.org/group/learn
first for these sort of questions.
One reason is that it interacts with constructs like
std.meta.staticMap, e.g.
alias constTypes(T ...) = staticMap!(ConstOf, T);
