You could do it that way (and it would be easier to archive them that way) 
but I went the other way around: executing the latest script builds the most 
recent object, and traversing the deltas backwards in time reverts to a 
previous version. That way I don't have to worry about the chain integrity 
losing my entire backup.

If you started with the full build script and then just stored delta scripts 
you could indeed update stacks that way. And diffs would still work. But... 
if anything along the way got messed up you'd have no way of building the 
delta chain to get to the most recent version.
