The default behavior for compat in xarray.combine_nested() is
"no_conflicts", which actually calls the fillna() method on variables
in a loop:
out = variables[0]
for var in variables[1:]:
out = out.fillna(var)
https://github.com/pydata/xarray/blob/55e5b5aaa6d9c27adcf9a7cb1f6ac3bf71c10dea/xarray/core/merge.py#L147-L149
This has quadratic behavior if the variables are stored in dask arrays
(the dask graph gets one element larger after each loop iteration).
