Looks good, but please add a test and a NEWS entry. The NEWS entry can be very terse, e.g.:
Improve error message when trying to call :func:`issubclass`
against a :class:`typing.Protocol` that has non-method members.
Patch by Randolph Sholz.
I created an issue for you to link your NEWS entry to.

Congrats on your first CPython contribution, @randolf-scholz! |
# Release 4.9.0 (December 9, 2023) This feature release adds `typing_extensions.ReadOnly`, as specified by PEP 705, and makes various other improvements, especially to `@typing_extensions.deprecated()`. There are no changes since 4.9.0rc1. # Release 4.9.0rc1 (November 29, 2023) - Add support for PEP 705, adding `typing_extensions.ReadOnly`. Patch by Jelle Zijlstra. - All parameters on `NewType.__call__` are now positional-only. This means that the signature of `typing_extensions.NewType.__call__` now exactly matches the signature of `typing.NewType.__call__`. Patch by Alex Waygood. - Fix bug with using `@deprecated` on a mixin class. Inheriting from a deprecated class now raises a `DeprecationWarning`. Patch by Jelle Zijlstra. - `@deprecated` now gives a better error message if you pass a non-`str` argument to the `msg` parameter. Patch by Alex Waygood. - `@deprecated` is now implemented as a class for better introspectability. Patch by Jelle Zijlstra. - Exclude `__match_args__` from `Protocol` members. Backport of python/cpython#110683 by Nikita Sobolev. - When creating a `typing_extensions.NamedTuple` class, ensure `__set_name__` is called on all objects that define `__set_name__` and exist in the values of the `NamedTuple` class's class dictionary. Patch by Alex Waygood, backporting python/cpython#111876. - Improve the error message when trying to call `issubclass()` against a `Protocol` that has non-method members. Patch by Alex Waygood (backporting python/cpython#112344, by Randolph Scholz).
