This is fine but maybe we should eat our dogfood and use typing_extensions.Sentinel.

Or if not, we could also just add a test for this. I know it's trivial code, but it doesn't really do any harm to test it explicitly, and it's nice to keep pragma: no cover exclusions to a minimum.

Dogfooding Sentinel sounds neat - I opened #657 to give that a try

Going through the current test coverage results, there's quite a bit of noise from things that are not expected to be executed or would not be meaningful to test. For example, dummy functions with placeholder bodies:
typing_extensions/src/test_typing_extensions.py
Lines 7788 to 7789 in e589a26
and unexpected error handling:
typing_extensions/src/test_typing_extensions.py
Lines 5958 to 5965 in e589a26
It would be nice to exclude these from the coverage report so that it's easier to see what's actually missing coverage.
This PR adds exclusions for:
