The ArrayBuffer `slice` method and TypedArray methods that create new ArrayBuffers (`filter`, `map`, `slice`, `toReversed`, etc.) make no effort to preserve immutability, just like they make no effort to preserve resizability (although use of SpeciesConstructor in those methods means that _lack_ of resizability/immutability in the result cannot be guaranteed for the latter).

Immutable buffers also [intuitively integrate with HTML `structuredClone`](https://github.com/whatwg/html/pull/11033)—they are not transferable, but cloning preserves both immutability and the underlying data block.
