Yeah, I was afraid of that lol. This must also be a pandas issue, too, since they recommend a similar way of extending pandas dataframes. I couldn't find a similar pandas issue/pr and was a bit surprised by that.

My temp solution is to use type narrowing:

def use_domain_specific_dataset(dset: xr.Dataset): if not isinstance(dset.ma, MyAccessor): raise something # gets some type checking dset.ma.my_special_func() Seems to at least provide the basic sanity checks
