I understand how you feel. I feel the same way. However, I have a
question to ask:
When? How long is "a good long time"? Forever?
The counter-argument is that there is no better time than now. The
reasons to keep 3DES there only get stronger as time goes on. This
problem becomes worse with time, not better.
