Interesting, I'm seeing the following for 3.12: ```shell FAILED bluesky/tests/test_utils.py::test_CallbackRegistry_1[class_method-False-True] - AssertionError: Incorrect number of signals ```

@tacaswell Is there any policy on deprecation? Numpy hasn't supported 3.8 for almost a year: https://endoflife.date/numpy, perhaps we should drop it
