I'm not sure what your point is, since I can't really tell what your
first sentence means. I can say that all the specific examples I
referred to began life as independent packages (available either on
the internet or as book supplements) and have subsequently become part
of the Mathematica proper.
I'm not particularly arguing that the RootSearch package should be
licensed by Wolfram Research. I'm simply stating the fact that there
is plenty of precedent for such a move.

I mean that, when given exact input, it returns exact results, rather
than numerical approximations. Even if a numerical integral is used
to determine the number of zeros (as in your example), the result is
exact. (Perhaps, I should have said exact. :) )
