That doesn't really change the problem: you're still forcing all local memory addresses to pay the additional price of a significant number of extra, constant zeroes only for the programming convenience of an addressing scheme unified with non-local memories that have totally different performance characteristics.

Hardware engineers "wasting" bandwidth and other resources in their design for software convenience? That doesn't sound very likely.
