Well, My guess is that it will take a loooong time, so long before that you 
might need to re-import your extract for whatever fail delete, style change, 
software update, and so on. Thus returning your database storage back to your 
extract's size only.

Note that a regular extract re-import is also a way to clean what is outside 
your zone of interest.

I think it is not possible to do it properly, a dirty hack loosing data from 
time to time could do but that will still require server ressources.
As said earlier here :
http://lists.openstreetmap.org/pipermail/dev/2012-August/025503.html
A share zone for regional diffs exports could do, or support for the new 
augmented diffs in those tools.
But both still have to be done.
