If I remember correctly, though, there was still a lot in question about legitimate use cases. The web-services cluster-safety use-case I sketched out here (http://mail.zope.org/pipermail/zope3-dev/2002-October/003112.html) is still (perhaps) a valid case, but ONLY in a very-carefully constructed application (and even that case leaves me wanting a better app-level way to do it).
I think I agree with the feeling that versions should stay in ZODB, but be depreciated/marked as "official evil" in ZMI.
