Thanks for the in-depth investigation!

As we can see from the above output, in netCDF4-python scaling is adapting the dtype to unsigned, not masking. This is also reflected in the docs unidata.github.io/netcdf4-python/#Variable.

Do we know why this is so?

If Xarray is trying to align with netCDF4-python it should separate mask and scale as netCDF4-python is doing. It does this already by using different coders but it doesn't separate it API-wise.
