xr.dot was implemented before dask/dask#3412 was merged, and thus it is not very efficient for dask now.

The proposed solution is to simply wait for dask/dask#3412 to reach the next release and then reimplement xarray.dot to use dask.array.einsum.

Agreed. I think the reimplementation would be easy, https://github.com/pydata/xarray/blob/99b457ce5859bd949cfea4671db5150c7297843a/xarray/core/computation.py#L1039-L1043 dask='parallelrized' -> dask='allow'
