In a new SDL, you won't be able to maintain 100% backward compatibility.
One possible thing that may be done is to create some external scene converter 
to recompose some droped features to the new features set, but that can be 
almost impossible in several cases. Ever tried to convert the droped "halo" 
feature to something else?
