Using the spatial functionality, I started an example of how we might approach this goal with a new branch.

import xcdat as xc
fn = '/p/css03/esgf_publish/CMIP6/CMIP/MIROC/MIROC-ES2L/historical/r6i1p1f2/Amon/tas/gn/v20200318/tas_Amon_MIROC-ES2L_historical_r6i1p1f2_gn_185001-201412.nc'
ds = xc.open_mfdataset(fn)
tas = ds('tas')
tas.spatial.average()

<xarray.DataArray 'tas' (time: 1980)> Size: 16kB
dask.array<truediv, shape=(1980,), dtype=float64, chunksize=(1,), chunktype=numpy.ndarray>

This is awesome! I'll take a closer look soon. Happy to see you got a working prototype.
