Proposed new feature or change:

I use the functionsnp.polynomial.polynomial.polyval2d andnp.polynomial.polynomial.polygrid2d onpint arrays. Pint makes use of thearray_function protocol to make the standard numpy function unit-aware. For that purpose I used to add thearray_function protocol to the mentioned functions myself by applyingarray_function_dispatch fromnumpy.core.overrides. But the entirecore module was recently made private so I suspect that this kind of monkey-patching is not supported any longer.
