Ok, this is
http://open-std.org/JTC1/SC22/WG21/docs/cwg_closed.html#1960
which says

"The rule was introduced because the hiding of a base class member by an
intermediate derived class is potentially intentional and should not be capable
of circumvention by a using-declaration in a derived class. The consensus of
CWG preferred not to change the restriction."

So yes, we need to fix this. :)
