I was just writing the exact same answer, but you beat me to it :) My
company for example is _forced_ not to use this switch, even though we
would _like_ to use it, but as you said, because of the centralized
flags management, we can't separately turn it on for code dependent on
boost and off for other code that doesn't like it.
That said, IMHO it should be on by default. Without it, users will not
be able to use some of the features in the library - for example,
lexical_cast will not allow usage of wide streams unless this flag is
