I just tested classgetitem defined via METHSTATIC and it works. This means we don't need to add slots. Thanks for the hint, Serhiy! Ivan, this might be worth mentioning in the PEP or in the docs.

I think it should be added to the PEP. Somehow I didn't think about C extensions, but now I see that it is important, also recently there appeared a lot of interest in better support of static typing for NumPy arrays and numeric stack. I will make a PR a bit later.
