It would be helpful to have __subclasshook__() implemented on the finders and loaders in importlib.abc, following the approach taken by ABCs in collections.abc. This came up relative to PEP-431, but would be generally useful (if only to a limited audience <wink>).

Here's a patch.

@ericsnowcurrently I opened a PR by reading your patch. Since the patch is a bit old, I couldn't add the
__subclasshook__for some classs because I got the deprecation warnings.ericsnowcurrently commentedon Mar 17, 2023
Thanks for doing that! I'll take a look when I get a chance.

Is this worth doing today, or would it be better to do #82963 ?
