Yes, it was never really intended that this be the case, but 
unfortunately in the build-up to JavaFX 2.0 we had to remove the 
SortedList implementation, so the fallback was to modify in place. As 
with every API decision it has its pluses and minuses, and supporters 
and detractors. Now that it is cast in stone we can only look forward to 
how best to support the SortedList and FilteredList concepts in JavaFX 8.0.
