Checking here to see if there would be any progress as we gladly see https://bugs.webkit.org/show_bug.cgi?id=277743 has been fixed and landed. Since multiple memory support has been implemented, Memory64 is the only left WASM feature to be supported, and this is the only feature lacking on Webkit to achieve parity with Chromium and Firefox on all Phase 5 standardised WebAssembly features.
