Functionality we provide in builtin io module is fairly minimal. Some code, including CPython stdlib, depends on more functionality. So, there's a choice to either implement it in C, or move it _io, and let implement other functionality in Python. 2nd choice is pursued. This setup matches CPython too (_io is builtin, io is Python-level).
