+1 for the general idea! It may be nice to have such a function which sits at the top level of the API, to fit into https://data-apis.org/array-api/draft/API_specification/data_type_functions.html nicely. However, ‘min_value’ or ‘min‘ won’t do then - we’d probably need to include ‘dtype’ in the name somewhere. But I don’t really like `np.min_dtype(dt)`. Maybe `np.min_dtype_value(dt)`?
