Any thoughts on the question in [1]?

I don't see why we are restricting to ground lists rather than using the 
safety definition to limit use of the list operator.

If we do retain ground lists then we could at least have a fn:list 
builtin which can be used to construct lists from elements, without 
having to use the ugly nested fn:insert-before(0,..) construction.
