if I were a 3pp, why would I reinvent the Artificer instead of some entirely new class. This seems to be an an argument for having all classes available (so you can create subclasses for all of them) more than for having all content available.Instead of reinventing the wheel over and over again because some subclasses (or classes like artificer) are closed content, publishers can built upon the set pieces and support them.
