Some confusion I feel - open-dated means that you still have to fix the routing in advance so that taxes etc can be priced in. Unless you change the routing there is no need for any ticket reissue.

I get all of my known/critical reservations in place often long before I actually think about issuing the ticket (which I normally do somewhere near the ticketing deadline, or even on departure for the first segment).

This is not hypothetical I have done this two or three times a year for the last 3-4 years.

Throwing one or more coupons away is no problem. What you can't do is use the coupons out of order - that should be picked up at check-in where the agent should look at the sequence number on the coupons, and I certainly wouldn't risk it in the hope they didn't notice.
