Yes, exactly! As I said:

There's an incredible package library out there, rivalling CPAN, and I love TeX and won't speak against it; but, if you try to step outside the package library (or even if you try to compose packages in sensible-seeming ways), as is very easy to do if you try to view TeX as a general-purpose typesetter, it rapidly becomes clear that there's a lot of magic going on that those packages hide away (more or less neatly, depending on their maturity), and that is hard to reproduce on your own, or add to.
