Then why bother spelling it "vector<bool>", if not to be used in a generic
and uniform context?  It is unlikely the committee is willing to swap one
specialization of vector<bool> for another.  I am well aware that there are
other ways to hack in std::real_bool (such as by using a traits class), but
it's still a hack.  If it is that important, propose a different class to
do this not spelled "vector<bool>".

For better or worse, that is the process.
