 WordPress has different utility functions to mark functions, methods,
 hooks, etc. in the core codebase as deprecated, and a dedicated file
 (`deprecated.php`) to move obsolete code to.

 I consider that it would be useful to introduce the approach of
 deprecating code to the unit tests as well.

 An example for obsolete code would be the `_unregister_post_type()` and
 `_unregister_taxonomy()` functions in the unit test utils. Since [36316],
 these test framework functions are only wrappers for core functions. As
 such, it would be appropriate to use the core functions in the tests, and
 deprecate the test framework functions.

 Let's explore how we could handle this in the unit test framework.
