@jhkennedy, how does this change look to you (for addressing the issue of upper bounds on dependencies)?

[danielfromearth]

Yes, exactly! Does xarray need the upper bound as well? For the upper bounds especially, the idea is they should communicate "this is a known or expected incompatibility"

I'm not sure why xarray didn't get updated when I ran poetry relax. Will manually check and update that one too.
