A comment on Writing an OS in Rust: Heap Allocation. Parent comment
Yes, I'm eagerly awaiting https://github.com/rust-lang/rust/pull/58457 and your follow-up https://github.com/rust-lang/rust/pull/60703. AFAIK, a global allocator is still required with them (so we still have to initialize it), but it allows us to choose a different allocator for some collections, e.g. to avoid deadlocks in interrupt handlers.
