This should of course not lead to confusion, however, there are operations that work with levels, e.g. da["level"] returns a mutltiindex level as virtual coordinate* and da.sel(level=5) works.

In my case I had Coordinates that looked something like this Coordinates: * time (time) datetime64[ns] ... * ens (ens) MultiIndex - model (ens) "CESM", "MIROC", ... - number (ens) 0, 1, ... and I wanted to do da.plot(x="time", y="number"), but this does currently not work. What I could do is ds.reset_index("ens") and use the resulting "non-dimension coordinate" for plotting.

(Both "non-dimension coordinate" and "MultiIndex" have some issues, so depending on what I want to do I need one ore the other.)

*which is why I only needed to change the valitity check for x and y and not the plotting itself
