Increasing energy efficiency, mayhaps, but running cold water in a shower for several min while you wait for it to heat up is not very water efficient.

And as the parent poster points out this is solved by using smaller pipes. * some of the hot water may cool while you wait so there may be a marginal amount of extra wastage at the outset.
