I'm not a big fan of having version numbers have some type of special meaning. To me, your post implies that there's a line in the sand at some magic version number with respect to due-diligence (on everyone's part). Gmail was in "beta" for years...it didn't mean anything. I understand that wiki and history disagrees with me, but it's still how I feel.
Oh, and there's a chance that yesterday's drama was a hoax: http://news.ycombinator.com/item?id=3205573
Edit:
Associating special meaning with these things has always been "gamed". Access went from 2 to 7. Heck, office went from 97 to 2000!
