I still can't find any mentions of external memory mapping without copying it into the heap. _Very_ disappointing as it makes yet another version of WASM completely unusable for many high-performance applications :(

The multi-memory proposal is your best bet for this: https://github.com/WebAssembly/multi-memory

It's supported in Wasmtime, WAVM, and WABT and wasm2c, and not much else so far (https://webassembly.org/roadmap/).
