Out of interest, why's that a bad thing? We have several editors, for  
example: each of them works differently and presents information  
differently. Why do we have to have One True Rollback?

I can foresee ways in which different "collapsing" methods could be of  
benefit - for example, one rollback tool might want to visualise (via  
animation) consecutive edits within a particular changeset to see what  
the user was doing.
