Frankly, if a huge project like Creator takes only 50 seconds on an old machine to do make -B -n, then I'd say for most projects (smaller than Creator) on most machines (newer than André said his is) in most circumstances (not full rebuilds), the time will be worth it.  Of course, you can always make the feature user-toggleable.  I, for one, would like to see it, as would the OP.
