The array api standard doesn't define any nan*-functions. xarray pretty much always defaults to using nan*-function. :(

So any time an array has a __array_namespace__ we have to use our own nan-solution, like for .sum: https://github.com/pydata/xarray/blob/d6d24507793af9bcaed79d7f8d3ac910e176f1ce/xarray/core/duck_array_ops.py#L288-L295

Any thoughts? Are there any clever ways to handle the aggregations with NaNs in a generic way?
