Emitting a DeprecationWarning every time ByteString is accessed or imported from collections.abc or typing is too noisy, as it effectively forbids anybody from doing from collections.abc import * or from typing import * if they want to avoid DeprecationWarnings. from typing import *, in particular, appears to be a common idiom so this looks as though it would be too disruptive. This was an error on my part; I'm sorry for the code churn here.

This PR reverts most of #104294, most of #104422, and all of #104416.

Thanks!

I tried to think of ideas to do this better and couldn't think of anything:

  • Remove ByteString from __all__ for 3.12: this would be a backward compatibility break
  • Change the import * code to suppress DeprecationWarnings: way too magical
  • In the module __getattr__, somehow detect that we're being called from import *: no idea how to do that elegantly
