For the same reason Boost.NumericConversion and Boost.Units are
independent. You're not proposing to make Boost.NumericConversion and
Boost.Units also parts of the convert() library, are you? Why do you
want to do this for the to- and from-string conversions?

The answer is the same as why I don't always use templates. I use
templates when I need my code to be generic, otherwise I do not.
If I want to convert to T I'll use convert<T> if I want to convert to
string, I prefer the much lighter s=to_string(x).
