That was my point. The current (broken/incomplete) code implements (1), Toon 
is suggesting that we should really be implementing (2).

I don't know enough crust frotran code[rs] to know which is most useful. 
However implementing (1) provides a very small cosmetic convenience that can 
already be achieved by other means, whereas (2) provides an additional 
feature that isn't available otherwise.
