What's better to work with the new Object or with the xarray accessor?

[alexlib]

VectorField is a new class that uses xarray underneath but could be masking xarray capabilities ? e.g. what would be the plot function that is already well done in xarray like colormap or quiver? vf = VectorField(); plt.quiver(vf) ?
xarray accessor used in pivpy keeps all the xarray extensions and use cases as they're, e.g. ds.piv.plot works like xarray.DataSet.plot

some packages provide dual use: https://github.com/xarray-contrib/xbatcher/blob/main/xbatcher/accessors.py for instance has its own Class and also xarray accessor.
