Why is it so? Is there some obvious performance improvement?
Instantiation and normal methods are generally a more intuitive coding style
than having only classmethods.
Also, it means you can have several instances with different parameters each,
and it eases testing (you can monkeypatch a test-specific instance without
disrupting the whole stuff).
