both array_ufunc and array_function will not work if the user passes in a Modin NumPy Array for out if we end up defaulting to NumPy. In the Modin NumPy API, I've fixed it so that we do copy in the values to a Modin NumPy Array, but I'm not sure what the solution should be for this, and so have defaulted to having it be unsupported.

I don't see where this "unsupported" is placed in code. I think it should be an exception or something similar, shouldn't it?

I think we should merge the .get and .pop like
out_kwarg = kwargs.pop("out", None)I see no point of keeping them separated

this seems to be losing converteg_args[0] (which was args[0]), feels weird

I can add a comment - but basically args[0] is self. Since we’re calling the function directly instead of calling the special method again, I’m passing in the converted self as the first argument, and only need to pass in any remaining args (after making sure to convert them)

a comment would be nice; also, if we're dropping converted_args[0], then we should probably be doing so in the upper loop and skip the call of args[0].__array__() altogether
