By the time the WAS tells us they're done, they've already detached and don't "feel" like they can get the attachment back. Some, may not want to risk feeling vulnerable again once they have built that protective shell. It requires a leap of faith that many of them are not willing to make. Couple that with the fact that some use an EA/PA to help them detach, and it becomes an almost impossible situation for the LBS.
That's why the changes don't necessarily matter to them.
