A question about exchanges and when withdrawing

[Acidyo]

Wouldn't it be a good idea to have an option to not be asked for a withdraw confirmation if you are withdrawing to the same address as last time?

That it saves the last address you already confirmed once and knows that it won't need to confirm the next time. Would this be too hard to implement?

I'm sure this would help the ones that don't want to have to confirm each time they withdraw from an exchange, or at least have an option that let's us do it.

No one had a comment on this?

No no no, this could be a bad options as people continue their pursuit of anonymity, in some way the exchange would need to save that address in its files and by doing that it associates your address with an account at the exchange.
I guess it could be a good thing but still the less information they have the better.
