I think there are three places where you would need to fix this:

Index based alignment in align(): https://github.com/pydata/xarray/blob/6d2076688d4f5466cf77ace2b196e910c1c0fbb8/xarray/core/alignment.py#L143

Unified dimensions for broadcasting variables, which is defined in two places: https://github.com/pydata/xarray/blob/6d2076688d4f5466cf77ace2b196e910c1c0fbb8/xarray/core/variable.py#L1978 https://github.com/pydata/xarray/blob/6d2076688d4f5466cf77ace2b196e910c1c0fbb8/xarray/core/computation.py#L441

The easiest work around is probably to call .squeeze() on any objects with size 1 dimensions -- then xarray's broadcasting/alignment should all work fine.
