Description
I've found it useful to broadcast to size-1 unlabeled dimensions. This allows you to avoid useless extra work in functions that accept unlabeled arrays, and would be very convenient when paired with apply_ufunc.
For example: https://github.com/xarray-contrib/flox/blob/ca576812e78b3978421eace6e9dde5a76729ebcc/flox/xarray.py#L45-L62
This should be paired with #2171

Research direction
Start by reading the flox example at xarray.py lines 45-62 and the related issue #2171 to understand the intended broadcasting behavior. Done means adding a broadcasting mode that inserts size-1 unlabeled dimensions and coordinating it with #2171.
