The user is free to use vector<char> or vector<int> if the space
optimization isn't wanted.

well, personally i used it for a prime sieve and for an application
where it was necessary to count the number of certain parts of a cube hit
by a point sequence.  in both cases, the space optimization was nice to
have.
