Adding support for this attribute view on macOS has been on the list for 
a long time but never bubbled to the top of anyone's list. So I don't 
think anyone has spent any time on it. One starting point is to look at 
the Linux implementation and see if it can be ported over. Discussion 
points will be whether the support is added to the BSD provider or the 
macOS provider, also details on the encoding of the attribute name.
