Wasm3 support / 64-bit support #146944

Description

After 3 years Wasm 3 now supports 64-bit address space and typed references, are there plans to improve the wasm64 target to make it as feature-complete as the wasm32 targets?

It sounds like many other languages are already targeting the new standard, it would be great if the Rust ecosystem could benefit too.

FYI https://doc.rust-lang.org/nightly/rustc/platform-support/wasm64-unknown-unknown.html
is still pointing to the outdated https://github.com/webassembly/memory64 proposal which has been archived in January.
