That's my understanding, at least, yeah.

I can see both points you're making. I think the message requesting address confirmation should've at least been emailed out to everyone on their list, because I think a lot of people who ordered at the start have forgotten altogether or just written it off as a lost cause and don't bother to check the site anymore.

And there definitely are a lot of logistical concerns, no question, but at the end of the day it's kinda a self-inflicted wound or at best a case of the publisher having bitten off more than they could chew without realizing just how large the project would end up being.
