At the ZODB level, creating a version is still a pretty intentional
act, right?  You must pass an explicit version name to the Connection
object, at which point all your modifications happen on that version.

I presume the misfeature is that you could mis-spell the version name
when calling Connection and effectively create a new version.  I'm not
sure I think that is a big deal.  If there was an explicit
createVersion() operation, then you're just as likely to misspell the
version when you call createVersion().
