The code pretending that all the selector classes exist and "implementing" them using SelectSelector was added in [1] because there was no facility to easily remove things from green version of modules (as far as I understand) - the facility has been added in [2] thus allowing us to make this change. As mentioned in the code I believe this approach is likely to be less confusing than the previous one (SelectSelector doesn't expose fileno() method that the other selectors have so it's not fully API-compatible with them).
