TI Power Management Produces Everyone Favourite Rechargeable Battery

Currently, Ni-mh batteries put out 1.2V whereas, non-recharegeable ones put out 1.5V - which is more end-product friendly. Question, why not embed a boost-regulator within in the battery package to put out 1.5V? Of course, you could put it in the electronics also, but this way, you could continue to use the new battery with old electronics.
