There are two different problems here:
1 - going back to a previous step in the configuration of a single package.
This would make the configmodule for packages a lot more complex
2 - going back to a previous package should not be that hard, just call
the configmodule again.
Of course the ultimate solution would be to have a language in which you
can formulate the decision process. Something like prolog would be suitable
I guess. I think that would be a too large step to implement at once though.
