One example is the extent of the heter of nidrai zeruzim (Nedarim 20b) which will change according to the expectations of average buyers and sellers – and perhaps also according to secular contract law. Another would be labor laws: the restrictions on an employee davening on his boss’s time (Berachos 16a) would, for instance, probably no longer apply.
