What I don't understand it, what is the difference between removing
the optimization words and removing the specialization +
supporting vector<bool>'s extra interfaces in vector<T> when T == bool.
The interfaces of the standard are reminded the same, exactly
the same.

Removing the performance words also makes vector<bool>
not functional, what's the differences?
