I'm now facing the equivalent problem with broadcast(). I need to concat 3 arrays:

python a = xarray.DataArray([[1,2],[3,4]], dims=['time', 'scenario'], coords={'time': ['t1', 't2']}) b = xarray.DataArray([5,6], dims=['time'], coords={'time': ['t3', 't4']}) c = xarray.DataArray(7, coords={'time': 't5'})

I want to broadcast dimension 'scenario' and concatenate on dimension 'time'. However, I can't invoke broadcast() because 1. a and b have misaligned time 2. c has a time coord, but not a time dim - if you broadcast a and c, you will get incorrect results

Again the solution would be to have an optional parameter exclude=['time']
