If that's true, then the overhead of a JOIN on an empty table would  
be significantly different than the join on a table that has a  
million rows in it, regardless of the filter criteria, yes?

I really like being able to enable/disable this by content type,  
particularly in light of the discussions regarding making more things  
nodes.  (user profiles, commments, etc).

Are we suggesting that the option goes a way or that revisions.module  
becomes required or dissapears, or are we talking about making  
revisions always on or always off?
