   - [likely should use](https://github.com/tc39/proposal-immutable-arraybuffer/issues/25) [Limited ArrayBuffer](https://github.com/tc39/proposal-limited-arraybuffer) instead of Immutable ArrayBuffer because Immutable ArrayBuffers cannot be detached.
   - Note that [`WebAssembly.Memory` also can't be detached (except via other WebAssembly methods,...)](https://github.com/tc39/proposal-immutable-arraybuffer/issues/20#issuecomment-2562075230).
