Description
FWIW one thing I'd be keen for to do generally — though maybe this isn't the place to start it — is handle warnings in the test suite when we add a new warning — i.e. filter them out where we expect them.
In this case, that would be the loading the netCDF files that have duplicate dims.
Otherwise warnings become a huge block of text without much salience. I mostly see the 350 lines of them and think "meh mostly units & cftime", but then something breaks on a new upstream release that was buried in there, or we have a supported code path that is raising warnings internally.
(I'm not sure whether it's possible to generally enforce that — maybe we could raise on any warnings coming from within xarray? Would be a non-trivial project to get us there though...)
