@fmaussion that's still helpful, thanks.

For cases where you want to do custom initialization, the suggestion (which I should add) is to simply write your own function to use in place of xarray.open_dataset.

Now that I think of it, it should also be possible to use some other in logic in __init__()—or even as a kludge store something like xarray_obj.attrs['_geoaccessor_state']—to determine whether the object is already, or needs to be, "initialized" (whatever that happens to mean for each accessor).

For instance, if the accessor creates and uses certain variables in a Dataset, it could check for their presence, and skip any initialization code if they already exist.
