DOC: Listing of all numpy functions that support __array_function__

Is there a listing of all numpy functions one would need to wrap to fully support all of the API that is wrappable via __array_function__? This seems like something that could be generated by introspection on the numpy source code and included in the numpy documentation, as far as I can see it doesn’t exist.

Having such a document to look at would make it much easier for downstream projects to add __array_function__ support. See https://github.com/yt-project/unyt/issues/139 for more details of my usage.

I like np.testing.overrides. I’d suggest having both implementation-independent functions that allow one to check whether a function can be overridden (say, overrides.allows_array_ufunc_override, overrides.allow_array_function_override), and exposed sets of all functions that allow it (say, overrides.functions and overrides.ufuncs).

One question is how to make this discoverable. I guess with the documentation of __array_ufunc__ and __array_function__ – maybe even add it to the relevant NEPs?

@ngoldbaum We discussed your request at today’s triage meeting. The NumPy dev team would like to help downstream projects to add __array_function__ support. What would be the best format to share the list of these functions with your project?
