Hmm, I don't think I understand the diference. Aren't you both in the capistrano case and the 'span codebase' example adding a table for example, so wouldn't both cases require repeating sql sequences?

Although maybe what you are saying is that you can make 'dumb' sql changes which break compatibility with past code vs 'smart' sql changes and code changes which are backwards compatible?
