Yes, you are right indeed.

Though, it's not that hard....
Yes.. it's hard to actually remove them completely as many IRC clients use acks, BUT..
like I said, what about making them optional?

Like.. let's say Khaled adds one more button (or perhaps a checkbox) to the DCC windows so that you can enable and disable the acks whenever you feel like - EVEN _during_ transfer??
I think that'd be the best way of doing it.

I hope Khaled reads this. =/
