The kind of liveness analysis done by the compiler is only helpful in extremely limited circumstances: when the compiler can track the slice from creation to destruction and when the slice never escapes in any way. I'm skeptical that such a case happens often enough to be worth implementing. (And even if we did implement it we would still have the above-mentioned problem that the allocator doesn't support discarding part of an allocation.)
