As I see it, you either have to disable the versioning functionality 
completely, or live with it. Raising a warning when people for instance 
add a Version object just gives the impression that you are safe if you 
don't use the Version product, which is wrong.

If the version functionality would be disabled by default and could be 
enabled by a startup parameter without impacting performance, then this 
would be the way to go IMHO.
