Description

Let status be SetIntegrityLevel(buffer, "frozen").

What does this accomplish?

Note that freezing an ArrayBuffer does not prevent mutating its data:

const ab = new ArrayBuffer(20);
Object.freeze(ab);
const ta = new Uint8Array(ab);
ta[0] = 5; // works fine

So I'm not sure why you'd want to freeze the buffer. A note in the spec would be helpful explaining the purpose.
