I'm fairly sure you do not lose the ability to version with 
DCOracleStorage, but I dont use versioning, so that's not something I 
lean on a lot.

The transient storage used for sessions in Zope 2.5+ is a non-versioning 
storage, however.

Versions are the ability to say "I'm going to 'fork' this object and 
work on it privately."  Versions can then be commited to the mainline. 
 However, versions don't play well with catalog data and thus are very 
infrequently used.
