IIUC, the versioning that Paul describes isn't the same thing as
versions in the ZODB.  Paul's thinking more along the lines of a
revision control system for content, which probably would not be
implemented with long-running ZODB versions.  I'm not even sure if it
would use multiple revision at the storage level to achieve this.

But I agree with the sentiments that ZODB versions ought to be
carefully examined and use cased for ZODB4.
