Or am I misreading that?
[[Evan Lloyd]] It does modify some shared lines. In practice this change became obvious once the previous one had been made. I'm not sure I understand what benefit you see in changing the order. I am, however, sure of the cost of rework and re-test. Do you really need this order change? How would you feel about our rolling them both together?
