It doesn't need to be used everywhere in every project.  The point is, if
you're starting something new, and you can be fairly sure that it's going to
be used for years to come, you can start a project with it.  I'm not
suggesting that you use it IN the boost libraries even.  I just see it as a
useful utility for anyone who would like to use it to keep their own code
clear.
